Greenplum Database 4.3.3 Release Notes

Greenplum Database 4.3.3 Release Notes

Rev: A03

Updated: March, 2015

Welcome to Pivotal Greenplum Database 4.3.3

Greenplum Database is a massively parallel processing (MPP) database server that supports next generation data warehousing and large-scale analytics processing. By automatically partitioning data and running parallel queries, it allows a cluster of servers to operate as a single database supercomputer performing tens or hundreds times faster than a traditional database. It supports SQL, MapReduce parallel processing, and data volumes ranging from hundreds of gigabytes, to hundreds of terabytes.

Note: This document contains pertinent release information about Greenplum Database 4.3.3. For previous versions of the release notes for Greenplum Database, go to Pivotal Documentation or EMC Support Zone.

About Greenplum Database 4.3.3

Product Enhancements

Managing Greenplum Database Objects and Data

  • The GRANT and REVOKE commands support the TRUNCATE privilege on a table.

    You can use the GRANT and REVOKE commands to allow or prohibit a Greenplum Database user or role from removing all the rows in a table with the TRUNCATE command.

    For information about GRANT and REVOKE, and TRUNCATE, see the Greenplum Database Reference Guide.

  • Capturing errors that occur from reading data from external data sources does not require an error table.

    You can capture formatting errors that occur from reading external data with the COPY command or with CREATE EXTERNAL TABLE by specifying the clause LOG ERRORS INTO error_table. In Greenplum Database 4.3.3, the clause INTO error-table is optional. If not specified, the errors are stored internally, not in a Greenplum Database error table.

    For errors that are stored internally in a log, use the built-in SQL function gp_read_error_log() to read the error log data. Use the built-in SQL function gp_truncate_error_log() to delete the error log data.

    For information about COPY and CREATE EXTERNAL TABLE, see the Greenplum Database Reference Guide. For information about external tables, see "Loading and Unloading Data" in the Greenplum Database Administrator Guide.

    Note: For the COPY and CREATE EXTERNAL TABLE commands, the INTO error-table clause is deprecated.
  • Greenplum Database 4.3.3 enables delta compression for compressed columns in append-optimized, column-oriented tables.

    For columns of type BIGINT, INTEGER, DATE, TIME, or TIMESTAMP, delta compression is also applied if the COMPRESSTYPE option is set to RLE-TYPE compression in an append-optimized, column-oriented table. The delta compression algorithm is based on the delta between consecutive column values and is designed to improve compression when data is loaded in sorted order or is when the compression is applied to column data that is in sorted order.

    For information about table compression, see the CREATE TABLE command in the Greenplum Database Reference Guide, and "Using Compression (Append-Optimized Tables Only)" in the Greenplum Database Administrator Guide

New Server Parameter to Control Reading External Data Error Limit

Greenplum Database stops processing input rows when you import data with the COPY command or from an external table if the first 1000 rows processed contain formatting errors. If a valid row is processed within the first n rows, Greenplum Database continues processing input rows. With Greenplum Database 4.3.3, you can change the default limit by setting the Greenplum Database server configuration parameter gp_initial_bad_row_limit.

For information about the server configuration parameter, see New Server Configuration Parameter. For information about COPY and CREATE EXTERNAL TABLE, see the Greenplum Database Reference Guide.

Greenplum Database Extension Enhancements

  • The Greenplum Database PL/R 2.0 extension package uses R 3.1.0.

    Greenplum Database 4.3.3 supports the PL/R 2.0 extension package that uses R 3.1.0. This page on the R web site describes the enhancements and changes to versions of R:

    http://cran.r-project.org/src/base/NEWS.html

    See the information in section CHANGES IN R 3.1.0 and earlier sections for information about changes in R 3.1.0 and earlier.

    For information about the PL/R Extension, see "Greenplum PL/R Extension" in the Greenplum Database Reference Guide. For information about extension compatibility, see Greenplum Database Extensions Compatibility.

  • The Greenplum Database 4.3.3 installation includes the Greenplum Database Fuzzy String Match Extension.

    The Greenplum Fuzzy String Match extension provides functions to determine similarities and distance between strings based on various algorithms. The Fuzzy String Match extension is based on the PostgreSQL fuzzystrmatch module.

    For information about the Fuzzy String Match Extension, see "Greenplum Fuzzy String Match Extension" in the Greenplum Database Reference Guide.

Backup and Restore Enhancements

For Greenplum Database 4.3.3, the gpcrondump and gpdbrestore utilities have been enhanced:

  • Support for Symantec NetBackup.

    For Greenplum Database running Red Hat Enterprise Linux, you can configure Greenplum Database to perform backup and restore operations with Symantec NetBackup. To perform a back up or restore with NetBackup, you configure Greenplum Database and NetBackup and then run a Greenplum Database gpcrondump or gpdbrestore utility.

  • Incremental backup support for NetBackup and Data Domain.

    The gpcrondump and gpdbrestore utilities support incremental backup when you use a Symantec NetBackup system or a Data Domain system.

    For incremental back up sets, a full backup and associated incremental backups, the backup set must be on a single device. For example, a backup set must all be on a file system. The backup set cannot have some backups on the local file system and others on a Data Domain system or a NetBackup system.

  • The gpcrondump utility supports customized email notification for backup operations.

    The gpcrondump utility can be configured to send out status email notifications after a backup operation completes. You can customize the email Subject and From lines of the email notifications that gpcrondump sends after a back up completes for a database.

  • The gpdbrestore utility analyzes only restored tables.

    In previous releases, the gpdbrestore utility ran the ANALYZE command on all tables in the database. You can disable analyzing restored tables with the gpdbrestore option --noanalyze.

For information about the Greenplum Database utilities gpcrondump and gpdbrestore, see the Greenplum Database Utility Guide. For information about backing up and restoring Greenplum Database, see "Backing Up and Restoring Databases " in the Greenplum Database Administrator Guide.

The gpload Utility Supports Table Schema Names

The Greenplum Database utility gpload supports specifying a schema name for the external table objects that are created when a load job is run. You specify the schema name in the YAML file that controls the load job with the EXTERNAL:SCHEMA property. See the Greenplum Database Utility Guide for information about the gpload utility and the YAML control file.

External Table Support for Hadoop Distributions

With Greenplum Database external tables created with the CREATE EXTERNAL TABLE command, you can specify the gphdfs protocol to access external files on an Hadoop file system (HDFS) as if they are regular database tables. For Greenplum Database 4.3.3, the gphdfs protocol has been enhanced to support these Hadoop distributions:
  • Pivotal Hadoop 2.0
  • Hortonworks Data Platform (HDP) 2.1
  • Cloudera 4.x and 5.x

For information about supported Hadoop distributions, see Hadoop Distribution Compatibility. For information about external tables, see "Loading and Unloading Data" in the Greenplum Database Administrator Guide.

Changed and Deprecated Features

Changed Features

New Server Configuration Parameter

For Greenplum Database 4.3.3, the parameter gp_initial_bad_row_limit controls how Greenplum Database processes input rows when errors occur while reading data from external data sources.

gp_initial_bad_row_limit 0 - INT_MAX 1000

For the parameter value n, Greenplum Database stops processing input rows when you import data with the COPY command or from an external table if the first n rows processed contain formatting errors. If a valid row is processed within the first n rows, Greenplum Database continues processing input rows.

Setting the value to 0 disables this limit.

The SEGMENT REJECT LIMIT clause can also be specified for the COPY command or the external table definition to limit the number of rejected rows.

INT_MAX is the largest value that can be stored as an integer on your system.

Resolved Issues in Greenplum Database 4.3.3

The table below lists issues that are now resolved in Greenplum Database 4.3.3.

For issues resolved in prior 4.3 releases, refer to the corresponding release notes available from Pivotal Network.

Table 4. Resolved Issues in 4.3.3
Issue Number Category Description
24479 Backup and Restore A table could not be restored (with the gpdbrestore -T option) from a back up that is on a Data Domain Boost system and that was created with the gpcrondump --ddboost options.
24478 Management Scripts: expansion The Greenplum Database gpexpand utility failed when an error table for an external table was present in Greenplum Database. The utility displayed this message:

DETAIL: ALTER TABLE is not allowed on error tables

24326 Query Execution, Storage Access Methods If either a non-partitioned append-only table or an individual append-only part of a partitioned table had more than 127 million rows on a segment, a query that uses an index to access the table data could return duplicate rows.

This issue has been fixed.

24317 Security Greenplum Database software has been updated to use OpenSSL 0.9.8zb in response to the OpenSSL Security Advisory [6 Aug 2014]. For information about the advisory, see https://www.openssl.org/news/secadv_20140806.txt.
24248 GPHDFS The Greenplum Database external table protocol gphdfs supports the Cloudera 4.x and 5.x HDFS distributions. See External Table Support for Hadoop Distributions.
24237 DDL and Utility Statements Temporary tables were not cleaned up properly in the following situation. A user defined function (UDF) was created with a security definer and that included statements to create the temporary table. The UDF was executed by a regular user who was given EXECUTE permission on the function.

This caused the temporary table to stay in the database after the session was disconnected.

24182 Management Scripts: General Greenplum Database timezone information has been updated to match world-wide timezones. For in formation about timezones, see http://www.iana.org/time-zones.
24168 Vacuum For an append-optimized table that did not contain any data, the VACUUM command did not update the value of relfrozenxid in the catalog table pg_class.
24158 Upgrade / Downgrade When upgrading Greenplum Database from a 4.2.x release to a 4.3.x release prior to 4.3.2.1, append-only tables were not correctly converted to append-optimized tables. In some cases, the incorrect conversion prevented the VACUUM command from reclaiming storage occupied by deleted tuples. For information about the upgrade issue, see Upgrading from 4.3.x to 4.3.3.
24119 Query Execution In some cases, a segmentation fault occurred when a DECLARE CURSOR WITH HOLD command was run by an ODBC driver.
24116

21042

Loaders: gpfdist The Greenplum Database gpfdist utility failed with a SIGSEGV error when the utility received a empty request with two consecutive return characters "\n\n".
24089 Loaders: Copy/ExternalTabs Multibyte characters were not handled properly when writing to an external table that uses the gb18030 encoding from a Greenplum database that was created with UTF8 encoding. In some cases, this error was encountered.

ERROR: The size of the value cannot be bigger than the field size value

24079 GPHDFS The Greenplum Database external table protocol gphdfs supports the Pivotal 2.0 distribution.

See External Table Support for Hadoop Distributions.

24068 Postgis When using PostGIS, In some cases a closed curved polygon that was converted to a linear polygon was not closed due to a linear approximation precision issue with PostGIS 2.0.3.
24067 Loaders: gpfdist, Loaders: gpload In some cases when network load was heavy, the Greenplum Database utility gpfdist intermittently failed with this error: gpfdist closed connection to server
24055 Vacuum The VACUUM FULL command transaction processing has been enhanced ensure proper operation with other concurrent operations.
24011 Catalog and Metadata, Vacuum In some cases, when a VACUUM FULL command was cancelled, incorrect handling of Greenplum Database transaction log caused a PANIC signal to be issued and prevented Greenplum Database from performing a crash recovery of a segment mirror.
24001 Backup and Restore During a backup operation, the Greenplum Database utility gpcrondump held an EXCLUSIVE lock on the catalog table pg_class longer than required.
23955 Query Execution In some query plans, where a window operator is under the right child of a nested loops join, wrong results could have been generated because of improper cleanup of the operator's internal state.
23925 Management Scripts: expansion, Management Scripts: General The Greenplum Database utilities gpactivatestandby and gpexpand used SSH to connect to localhost (the Greenplum Database host where the utility was run). Using SSH was redundant as the command was already on the local host and has been eliminated.
23894 Backup and Restore Performing a back up to a Data Domain system failed when the Greenplum Database utility gpcrondump command specified the --ddboost options because gpcrondump performed a disk space check.
23864 Catalog and Metadata Running the REINDEX command on a database while other workloads are concurrently running could create inconsistencies in the database catalog.
23850 Management Scripts In some cases after expanding a Greenplum Database system, running gpinitstandby -n failed to resynchronize the data between the primary and standby master host.
23850 Management Scripts: General In some cases after expanding a Greenplum Database system, running gpinitstandby -n failed to resynchronize the data between the primary and standby master host.
23842 Replication: Segment Mirroring In some rare cases, if a restart occurred while the gprecoverseg utility was running, some tables and a persistent table were detected having less data on a mirror segment that corresponds to a primary segment.
23802 Query Execution Greenplum Database did not manage temporary workfiles (spill files) properly. In some cases, this caused a query that required workfiles to fail with a message that stated that a Greenplum Database segment had reached the maximum configured workfile usage limit.
23753 Backup and Restore The emails sent by the Greenplum Database gpcrondump utility could not be customized. Now the utility supports customized email notification for backup operations. See Backup and Restore Enhancements.
23730 Backup and Restore, Management Scripts: master mirroring When configuring a Greenplum Database system with a standby master, the gpinitstandby utility did not correctly update the pg_hba.conf file on Greenplum Database segment hosts.
23729 Backup and Restore, DDL and Utility Statements When the -b option was specified with the gpcrondump utility to disable a disk space check, a check was still performed.
23717 Locking, Signals, Processes During Greenplum Database shutdown, a signal-unsafe function call was called from a signal handler function. The signal-unsafe function was replaced.
23699 Monitoring: gpperfmon server Greenplum Database failed when the gpperfmon log files were not encoded in UTF8.

This issue has been resolved.

23637 Backup and Restore When restoring a Greenplum database with the Greenplum Database gpcrondump utility, the utility performed an ANALYZE operation on the entire database. Now the gpcrondump utility analyzes only the restored tables. See Backup and Restore Enhancements.
23568 Backup and Restore When backing up a Greenplum database with the Greenplum Database gpcrondump utility and specifying an NFS directory with the -u option, the gpcrondump utility created an empty db_dumps directory in the master and segment data directories.
23558 Backup and Restore When restoring a backup from a Data Domain system using --ddboost options, the Greenplum Database gpdbrestore utility failed because it could not find C data and post data files.
23286 Dispatch In some cases, Greenplum Database did not handle the processing of cancelled distributed queries properly.

This issue has been resolved.

22974 Loaders: Copy/ExternalTabs When reading data from external sources, Greenplum Database stopped reading data if the first 1000 rows processed contain formatting errors. Now the limit is configurable. See New Server Parameter to Control Reading External Data Error Limit.
20504 Query Execution FOR loops in PL/pgSQL did not close the sequence generator if further access was still required.
18562 DDL and Utility Statements A transaction lock did not block reader processes from proceeding when a writer process was holding the same lock. In some cases this caused a race condition to occur.

Now, Greenplum Database blocks reader processes when a writer process holds the same lock to prevent race conditions from occurring.

17264 Replication: Segment Mirroring In some cases, Greenplum Database continuously logged this message when sending file replication process statistics to Greenplum Database perfmon process:

Error when sending file rep stats to perfmon

16450 Backup and Restore When running the Greenplum Database utility pg_dumpall with the option --resource-queues to create scripts that contain resource queue definitions, the utility generated incorrect scripts when the resource queue definition contained the memory_limit option.
16059 Resource Management Some SQL statements that executed a PL/pgSQL function that contained an insert, update, or delete operation did not allocate memory correctly. This caused the following issues:
  • Decreased performance
  • Large number of spill files were created on disk

This issue has been resolved.

Known Issues in Greenplum Database 4.3.3

This section lists the known issues in Greenplum Database 4.3.3. A workaround is provided where applicable.

For known issues discovered in previous 4.3.x releases, see the release notes at Pivotal Network. For known issues discovered in other previous releases, including patch releases to Greenplum Database 4.2.x, 4.1 or 4.0.x, see the corresponding release notes, available from EMC Support Zone:

Table 5. All Known Issues in 4.3.3
Issue Category Description
24383 gphdfs Greenplum Database external tables do not support using the gphdfs protocol and MapR to access HDFS data.
24264 Catalog and Metadata The commands REINDEX TABLE table_name and REINDEX INDEX index_name do not re-index child partition indexes of a partitioned table.

Workaround: Run REINDEX on the child tables of the partitioned table.

24588 Management Scripts: gpconfig The Greenplum Database gpconfig utility does not display the correct information for the server configuration parameter gp_enable_gpperfmon. The parameter displays the state of the Greenplum Command Center data collection agents (gpperfmon).

Workaround: The SQL command SHOW displays the correct gp_enable_gpperfmon value.

22798 Management Scripts: expansion, Management Scripts: master mirroring If it is not possible to use SSH to connect from the Greenplum Database master host to 'localhost' a failure occurs when running the Greenplum Database gpactivatestandby or gpexpand utility because of an SSH failure.

Workaround: Enable SSH to 'localhost' on the master host to work around this issue.

23646 DML Running an UPDATE command after a DROP COLUMN and ADD PARTITION command on a partitioned table causes a Greenplum Database segment instance failure.
24031 gphdfs If a readable external table is created with FORMAT 'CSV' and uses the gphdfs protocol, reading a record fails if the record spans multiple lines and the record is stored in multiple HDFS blocks.

Workaround: Remove line separators from within the record so that the record does not span multiple lines.

23924 Backup and Restore In some cases, performing some operations on an append-optimized table and then performing a full backup with the gpcrondump utility to a Data Domain system with DDBoost fails with this error:

ERROR: relation "file_name" does not exist

23824 Authentication In some cases, LDAP client utility tools cannot be used after running the source command:

source $GPHOME/greenplum_path.sh

because the LDAP libraries included with Greenplum Database are not compatible with the LDAP client utility tools that are installed with operating system.

Workaround: The LDAP tools can be used without running the source command in the environment.

23525 Query Planner Some SQL queries that contain sub-selects fail with this error.

ERROR: Failed to locate datatype for paramid 0

22792 Build Greenplum Database is not certified on Red Hat Enterprise Linux 5.10.
22215 Build Greenplum Database is not certified with these connectivity drivers:

Data Direct v 7.022; PowerExchange for Greenplum 9.5.1

32-bit Microstrategy ODBC for Greenplum Wire Protocol 6.10.01.80

Open source ODBC 9.01.0100 and JDBC 9.1.902 Type 4

SAS/ACCESS 9.3 driver provided with SAS software2

23366 Resource Management In Greenplum Database 4.2.7.0 and later, the priority of some running queries, cannot be dynamically adjusted with the gp_adjust_priority() function. The attempt to execute this request might silently fail. The return value of the gp_adjust_priority() call indicates success or failure. If 1 is returned, the request was not successfully executed. If a number greater than 1 is returned, the request was successful. If the request fails, the priority of all running queries are unchanged, they remain as they were before the gp_adjust_priority() call.
23492 Backup and Restore A backup from a Greenplum Database 4.3.x system that is created with a Greenplum Database back up utility, for example gpcrondump, cannot be restored to a Greenplum Database 4.2.x system with the psql utility or the corresponding restore utility, for example gpdbrestore.
23521 Client Access Methods and Tools Hadoop YARN based on Hadoop 2.2 or later does not work with Greenplum Database.

Workaround: For Hadoop distributions based on Hadoop 2.2 or later that are supported by Greenplum Database, the classpath environment variable and other directory paths defined in $GPHOME/lib/hadoop/hadoop_env.sh must be to be modified so that the paths point to the appropriate JAR files.

21917 Replication: Segment Mirroring In some rare cases after the Greenplum Database utility gprecoverseg was run, some append-optimized tables and a persistent table were detected having less data on a mirror segment corresponding to a primary segment.
20453 Query Planner For SQL queries of either of the following forms:
SELECT columns FROM table WHERE table.column NOT IN subquery;
SELECT columns FROM table WHERE table.column = ALL subquery;
tuples that satisfy both of the following conditions are not included in the result set:
  • table.column is NULL.
  • subquery returns the empty result.
21724 Query Planner Greenplum Database executes an SQL query in two stages if a scalar subquery is involved. The output of the first stage plan is fed into the second stage plan as a external parameter. If the first stage plan generates zero tuples and directly contributes to the output of the second stage plan, incorrect results might be returned.
21838 Backup and Restore When restoring sets of tables with the Greenplum Database utility gpdbrestore, the table schemas must be defined in the database. If a table’s schema is not defined in the database, the table is not restored. When performing a full restore, the database schemas are created when the tables are restored.

Workaround: Before restoring a set of tables, create the schemas for the tables in the database.

21129 DDL and Utility Statements SSL is only supported on the master host. It is not supported on segment hosts.
20822 Backup and Restore Special characters such as !, $, #, and @ cannot be used in the password for the Data Domain Boost user when specifying the Data Domain Boost credentials with the gpcrondump options --ddboost-host and --ddboost-user.
18247 DDL and Utility Statements TRUNCATE command does not remove rows from a sub-table of a partitioned table. If you specify a sub-table of a partitioned table with the TRUNCATE command, the command does not remove rows from the sub-table and its child tables.

Workaround: Use the ALTER TABLE command with the TRUNCATE PARTITION clause to remove rows from the sub-table and its child tables.

19788 Replication: Resync, Transaction Management In some rare circumstances, performing a full recovery with gprecoverseg fails due to inconsistent LSN.

Workaround: Stop and restart the database. Then perform a full recovery with gprecoverseg.

19705 Loaders: gpload gpload fails on Windows XP with Python 2.6.

Workaround: Install Python 2.5 on the system where gpload is installed.

19493

19464

19426

Backup and Restore The gpcrondump and gpdbrestore utilities do not handle errors returned by DD Boost or Data Domain correctly.
These are two examples:
  • If invalid Data Domain credentials are specified when setting the Data Domain Boost credentials with the gpcrondump utility, the error message does not indicate that invalid credentials were specified.
  • Restoring a Greenplum database from a Data Domain system with gpdbrestore and the --ddboost option indicates success even though segment failures occured during the restore.

Workaround: The errors are logged in the master and segment server backup or restore status and report files. Scan the status and report files to check for error messages.

15692

17192

Backup and Restore Greenplum Database’s implementation of RSA lock box for Data Domain Boost changes backup and restore requirements for customers running SUSE.

The current implementation of the RSA lock box for Data Domain Boost login credential encryption only supports customers running on Red Hat Enterprise Linux.

Workaround: If you run Greenplum Database on SUSE, use NFS as your backup solution. See the Greenplum Database Administrator Guide for information on setting up a NFS backup.

18850 Backup and Restore Data Domain Boost credentials cannot be set up in some environments due to the absence of certain libraries (for example, libstdc++) expected to reside on the platform.

Workaround: Install the missing libraries manually on the system.

18851 Backup and Restore When performing a data-only restore of a particular table, it is possible to introduce data into Greenplum Database that contradicts the distribution policy of that table. In such cases, subsequent queries may return unexpected and incorrect results. To avoid this scenario, we suggest you carefully consider the table schema when performing a restore.
18713 Catalog and Metadata Drop language plpgsql cascade results in a loss of gp_toolkit functionality.

Workaround: Reinstall gp_toolkit.

18710 Management Scripts Suite Greenplum Management utilities cannot parse IPv6 IP addresses.

Workaround: Always specify IPv6 hostnames rather than IP addresses

18703 Loaders The bytenum field (byte offset in the load file where the error occurred) in the error log when using gpfdist with data in text format errors is not populated, making it difficult to find the location of an error in the source file.
12468 Management Scripts Suite gpexpand --rollback fails if an error occurs during expansion such that it leaves the database down

gpstart also fails as it detects that expansion is in progress and suggests to run gpexpand --rollback which will not work because the database is down.

Workaround: Run gpstart -m to start the master and then run rollback.

18785 Loaders Running gpload with the --ssl option and the relative path of the source file results in an error that states the source file is missing.

Workaround: Provide the full path in the yaml file or add the loaded data file to the certificate folder.

18414 Loaders Unable to define external tables with fixed width format and empty line delimiter when file size is larger than gpfdist chunk (by default, 32K).
14640 Backup and Restore gpdbrestore outputting incorrect non-zero error message.

When performing single table restore, gpdbrestore gives warning messages about non-zero tables however prints out zero rows.

17285 Backup and Restore NFS backup with gpcrondump -c can fail.

In circumstances where you haven't backed up to a local disk before, backups to NFS using gpcrondump with the -c option can fail. On fresh systems where a backup has not been previously invoked there are no dump files to cleanup and the -c flag will have no effect.

Workaround: Do not run gpcrondump with the -c option the first time a backup is invoked from a system.

17837 Upgrade/ Downgrade Major version upgrades internally depend on the gp_toolkit system schema. The alteration or absence of this schema may cause upgrades to error out during preliminary checks.

Workaround: To enable the upgrade process to proceed, you need to reinstall the gp_toolkit schema in all affected databases by applying the SQL file found here: $GPHOME/share/postgresql/gp_toolkit.sql.

17513 Management Scripts Suite Running more than one gpfilespace command concurrently with itself to move either temporary files (--movetempfilespace) or transaction files (--movetransfilespace) to a new filespace can in some circumstances cause OID inconsistencies.

Workaround: Do not run more than one gpfilespace command concurrently with itself. If an OID inconsistency is introduced gpfilespace --movetempfilespace or gpfilespace --movetransfilespace can be used to revert to the default filespace.

17780 DDL/DML: Partitioning ALTER TABLE ADD PARTITION inheritance issue

When performing an ALTER TABLE ADD PARTITION operation, the resulting parts may not correctly inherit the storage properties of the parent table in cases such as adding a default partition or more complex subpartitioning. This issue can be avoided by explicitly dictating the storage properties during the ADD PARTITION invocation. For leaf partitions that are already afflicted, the issue can be rectified through use of EXCHANGE PARTITION.

17795 Management Scripts Suite Under some circumstances, gppkg on SUSE is unable to correctly interpret error messages returned by rpm.

On SUSE, gppkg is unable to operate correctly under circumstances that require a non-trivial interpretation of underlying rpm commands. This includes scenarios that result from overlapping packages, partial installs, and partial uninstalls.

17604 Security A Red Hat Enterprise Linux (RHEL) 6.x security configuration file limits the number of processes that can run on gpadmin.

RHEL 6.x contains a security file (/etc/security/limits.d/90-nproc.conf) that limits available processes running on gpadmin to 1064.

Workaround: Remove this file or increase the processes to 131072.

17415 Installer When you run gppkg -q -info<some gppkg>, the system shows the GPDB version as main build dev.
17334 Management Scripts Suite You may see warning messages that interfere with the operation of management scripts when logging in.

Greenplum recommends that you edit the /etc/motd file and add the warning message to it. This will send the messages to are redirected to stdout and not stderr. You must encode these warning messages in UTF-8 format.

17221 Resource Management Resource queue deadlocks may be encountered if a cursor is associated with a query invoking a function within another function.
17113 Management Scripts Suite Filespaces are inconsistent when the Greenplum database is down.

Filespaces become inconsistent in case of a network failure. Greenplum recommends that processes such as moving a filespace be done in an environment with an uninterrupted power supply.

17189 Loaders: gpfdist gpfdist shows the error “Address already in use” after successfully binding to socket IPv6.

Greenplum supports IPv4 and IPv6. However, gpfdist fails to bind to socket IPv4, and shows the message “Address already in use”, but binds successfully to socket IPv6.

16519 Backup and Restore Limited data restore functionality and/or restore performance issues can occur when restoring tables from a full database backup where the default backup directory was not used.

In order to restore from backup files not located in the default directory you can use the -R option to point to another host and directory. This is not possible however, if you want to point to a different directory on the same host (NFS for example).

Workaround: Define a symbolic link from the default dump directory to the directory used for backup, as shown in the following example:
  1. Perform a full Database Backup to a specific NFS directory:
       $ gpcrondump -x <db_name> -z -u /backup/DCA-93 -a
  2. Create a file listing the segment servers:
       $ vi /home/gpadmin/segments
       sdw1
       sdw2
       sdw3
       …
  3. Remove the relevant date folder from db_dumps directories on the master and segments:
       $ rm -r /data/master/gpseg-1/db_dumps/20120619
       $ gpssh -f segments 'rm -r /data1/primary/gpseg*/db_dumps/20120619'
       $ gpssh -f segments 'rm -r /data2/primary/gpseg*/db_dumps/20120619'
  4. Create a symbolic link between the master and segment directories and the directory to which you backed up in step 1. Only the master and sdw1 was shown here, write a script for the remaining segments:
       $ ln -s /backup/DCA-93/db_dumps/20120619/data/master/gpseg-1/db_dumps/20120619
       $ gpssh -h sdw1 'ln -s /backup/DCA-93/db_dumps/20120619/data1/primary/gpseg0/db_dumps/20120619'
       $ gpssh -h sdw1 'ln -s /backup/DCA-93/db_dumps/20120619/data1/primary/gpseg1/db_dumps/20120619'
       $ gpssh -h sdw1 'ln -s /backup/DCA-93/db_dumps/20120619/data1/primary/gpseg2/db_dumps/20120619'
       $ gpssh -h sdw1 'ln -s /backup/DCA-93/db_dumps/20120619/data2/primary/gpseg3/db_dumps/20120619'
       $ gpssh -h sdw1 'ln -s /backup/DCA-93/db_dumps/20120619/data2/primary/gpseg4/db_dumps/20120619'
       $ gpssh -h sdw1 'ln -s /backup/DCA-93/db_dumps/20120619/data2/primary/gpseg5/db_dumps/20120619'
  5. Restore from backup files:
       $ gpdbrestore -t 20120619061835 -T <schema.table> -a
  6. Remove the symbolic links:
       $ rrm -r /data/master/gpseg-1/db_dumps/20120619
       $ gpssh -f segments 'rm -r /data1/primary/gpseg*/db_dumps/20120619'
       $ gpssh -f segments 'rm -r /data2/primary/gpseg*/db_dumps/20120619'
16064 Backup and Restore Restoring a compressed dump with the --ddboost option displays incorrect dump parameter information.

When using gpdbrestore --ddboost to restore a compressed dump, the restore parameters incorrectly show “Restore compressed dump = Off”. This error occurs even if gpdbrestore passes the --gp-c option to use gunzip for in-line de-compression.

15899 Backup and Restore When running gpdbrestore with the list (-L) option, external tables do not appear; this has no functional impact on the restore job.

Upgrading to Greenplum Database 4.3.3

The upgrade path supported for this release is Greenplum Database 4.2.x.x to Greenplum Database 4.3.3. The minimum recommended upgrade path for this release is from Greenplum Database version 4.2.x.x. If you have an earlier major version of the database, you must first upgrade to version 4.2.x.x.

Prerequisites

Before starting the upgrade process, Pivotal recommends the following:

  • Verify the health of the Greenplum Database host hardware, and that you verify that the hosts meet the requirements for running Greenplum Database. The Greenplum Database gpcheckperf utility can assist you in confirming the host requirements.
  • Run the gpcheckcat utility to check for Greenplum Database catalog inconsistencies. The utility is in $GPHOME/bin/lib. Pivotal recommends that Greenplum Database be in restricted mode when you run gpcheckcat utility. See the Greenplum Database Utility Guide for information about the gpcheckcat utility.

    If gpcheckcat reports catalog inconsistencies, you can run gpcheckcat with the -g option to generate SQL scripts to fix the inconsistencies.

    After you run the SQL scripts, run gpcheckcat again. You might need to repeat the process of running gpcheckcat and creating SQL scripts to ensure that there are no inconsistencies. Pivotal recommends that the SQL scripts generated by gpcheckcat be run on a quiescent system. The utility might report false alerts if there is activity on the system.

    Important: If the gpcheckcat utility reports errors, but does not generate a SQL script to fix the errors, contact Pivotal support. Information for contacting Pivotal Support is at https://support.pivotal.io.

For detailed upgrade procedures and information, see the following sections:

If you are utilizing Data Domain Boost, you have to re-enter your DD Boost credentials after upgrading from Greenplum Database 4.2.x.x to 4.3 as follows:

gpcrondump --ddboost-host ddboost_hostname --ddboost-user ddboost_user
Note: If you do not reenter your login credentials after an upgrade, your backup will never start because the Greenplum Database cannot connect to the Data Domain system. You will receive an error advising you to check your login credentials.

Upgrading from 4.3.x to 4.3.3

An upgrade from 4.3.x to 4.3.3 involves stopping Greenplum Database, updating the Greenplum Database software binaries, and restarting Greenplum Database.

Note: If you are upgrading from Greenplum Database between 4.3.0 and 4.3.2, run the fix_ao_upgrade.py utility to check Greenplum Database for the upgrade issue and fix the upgrade issue (See step 9). The utility is in this Greenplum Database 4.3.3 directory: $GPHOME/share/postgresql/upgrade

For information about the utility, see fix_ao_upgrade.py Utility.

  1. Log in to your Greenplum Database master host as the Greenplum administrative user:
    $ su - gpadmin
  2. Uninstall the Greenplum Database gNet extension package if it is installed.

    The gNet extension package contains the software for the gphdfs protocol. For Greenplum Database 4.3.1 and later releases, the extension is bundled with Greenplum Database. The files for gphdfs are installed in $GPHOME/lib/hadoop.

  3. Perform a smart shutdown of your current Greenplum Database 4.3.x system (there can be no active connections to the database):
    $ gpstop
  4. Run the installer for 4.3.3 on the Greenplum Database master host. When prompted, choose an installation location in the same base directory as your current installation. For example:
    /usr/local/greenplum-db-4.3.3.0
  5. Edit the environment of the Greenplum Database superuser (gpadmin) and make sure you are sourcing the greenplum_path.sh file for the new installation. For example change the following line in .bashrc or your chosen profile file:
    source /usr/local/greenplum-db-4.3.0.0/greenplum_path.sh

    to:

    source /usr/local/greenplum-db-4.3.3.0/greenplum_path.sh

    Or if you are sourcing a symbolic link (/usr/local/greenplum-db) in your profile files, update the link to point to the newly installed version. For example:

    $ rm /usr/local/greenplum-db
    $ ln -s /usr/local/greenplum-db-4.3.3.0 /usr/local/greenplum-db
  6. Source the environment file you just edited. For example:
    $ source ~/.bashrc
  7. Run the gpseginstall utility to install the 4.3.3 binaries on all the segment hosts specified in the hostfile. For example:
    $ gpseginstall -f hostfile
  8. After all segment hosts have been upgraded, you can log in as the gpadmin user and restart your Greenplum Database system:
    $ su - gpadmin
    $ gpstart
  9. If you are upgrading a version of Greenplum Database between 4.3.0 and 4.3.2, check your Greenplum Database for inconsistencies due to an incorrect conversion of 4.2.x append-only tables to 4.3.x append-optimized tables.
    Important: The Greenplum Database system must be started but should not be running any SQL commands while the utility is running.
    1. Run the fix_ao_upgrade.py utility with the option --report. The following is an example.
      $ $GPHOME/share/postgresql/upgrade/fix_ao_upgrade.py --host=mdw --port=5432 --report
    2. If the utility displays a list of inconsistencies, fix them by running the fix_ao_upgrade.py utility without the --report option.
      $ $GPHOME/share/postgresql/upgrade/fix_ao_upgrade.py --host=mdw --port=5432
    3. (optional) Run the fix_ao_upgrade.py utility with the option --report again. No inconsistencies should be reported.
  10. If you are utilizing Data Domain Boost, you have to re-enter your DD Boost credentials after upgrading from Greenplum Database 4.3.x to 4.3.3 as follows:
    gpcrondump --ddboost-host ddboost_hostname --ddboost-user ddboost_user
Note: If you do not reenter your login credentials after an upgrade, your backup will never start because the Greenplum Database cannot connect to the Data Domain system. You will receive an error advising you to check your login credentials.

fix_ao_upgrade.py Utility

The fix_ao_upgrade.py utility checks Greenplum Database for an upgrade issue that is caused when upgrading Greenplum Database 4.2.x to a version of Greenplum Database between 4.3.0 and 4.3.2.

The upgrade process incorrectly converted append-only tables that were in the 4.2.x database to append-optimized tables during an upgrade from Greenplum Database 4.2.x to a Greenplum Database 4.3.x release prior to 4.3.2.1. The incorrect conversion causes append-optimized table inconsistencies in the upgraded Greenplum Database system.

Syntax
fix_ao_upgrade.py {-h master_host | --host=master_host}
     {-p master_port | --port=master_port}
     [-u user | --user=user ]
     [--report] [-v | --verbose] [--help]
Options
-r | --report
Report inconsistencies without making any changes.
-h master_host | --host=master_host
Greenplum Database master hostname or IP address.
-p master_port | --port=master_port
Greenplum Database master port.
-u user | --user=user
User name to connect to Greenplum Database. The user must be a Greenplum Database superuser. Default is gpadmin.
v | --verbose
Verbose output that includes table names.
--help
Show the help message and exit.

If you specify the optional --report option, the utility displays a report of inconsistencies in the Greenplum Database system. No changes to Greenplum Database system are made. If you specify the --verbose option with --report, the table names that are affected by the inconsistencies are included in the output.

Upgrading from 4.2.x.x to 4.3.3

This section describes how you can upgrade from Greenplum Database 4.2.x.x or later to Greenplum Database 4.3.3. For users running versions prior to 4.2.x.x of Greenplum Database, see the following:

Planning Your Upgrade

Before you begin your upgrade, make sure the master and all segments (data directories and filespace) have at least 2GB of free space.

Prior to upgrading your database, Pivotal recommends that you run a pre-upgrade check to verify your database is healthy.

You can perform a pre-upgrade check by executing the gpmigrator (_mirror) utility with the --check-only option.

For example:

source $new_gphome/greenplum_path.sh; 
gpmigrator_mirror --check-only $old_gphome $new_gphome
Note: Performing a pre-upgrade check of your database with the gpmigrator (_mirror) utility should done during a database maintenance period. When the utility checks the database catalog, users cannot access the database.

Migrating a Greenplum Database That Contains Append-Only Tables

The migration process updates append-only tables that are in a Greenplum Database to append-optimized tables. For a database that contains a large number of append-only tables, the conversion to append-optimized tables might take a considerable amount of time.

Append-optimized tables are introduced in Greenplum Database 4.3.0. For information about append-optimized tables, see the release notes for Greenplum Database 4.3.0.

Upgrade Procedure

This section divides the upgrade into the following phases: pre-upgrade preparation, software installation, upgrade execution, and post-upgrade tasks.

We have also provided you with an Upgrade Checklist that summarizes this procedure.

Important: Carefully evaluate each section and perform all required and conditional steps. Failing to perform any of these steps can result in an aborted upgrade, placing your system in an unusable or even unrecoverable state.
Pre-Upgrade Preparation (on your 4.2.x system)

Perform these steps on your current 4.2.x Greenplum Database system. This procedure is performed from your Greenplum master host and should be executed by the Greenplum superuser (gpadmin).

  1. Log in to the Greenplum Database master as the gpadmin user:
    $ su - gpadmin
  2. (optional) Vacuum all databases prior to upgrade. For example:
    $ vacuumdb database_name
  3. (optional) Clean out old server log files from your master and segment data directories. For example, to remove log files from 2011 from your segment hosts:
    $ gpssh -f seg_host_file -e 'rm /gpdata/*/gp*/pg_log/gpdb-2011-*.csv'

    Running Vacuum and cleaning out old logs files is not required, but it will reduce the size of Greenplum Database files to be backed up and migrated.

  4. Run gpstate to check for failed segments.
    $ gpstate
    
  5. If you have failed segments, you must recover them using gprecoverseg before you can upgrade.
    $ gprecoverseg
    

    Note: It might be necessary to restart the database if the preferred role does not match the current role; for example, if a primary segment is acting as a mirror segment or a mirror segment is acting as a primary segment.

  6. Copy or preserve any additional folders or files (such as backup folders) that you have added in the Greenplum data directories or $GPHOME directory. Only files or folders strictly related to Greenplum Database operations are preserved by the migration utility.
Install the Greenplum Database 4.3 Software Binaries
  1. Download or copy the installer file to the Greenplum Database master host.
  2. Unzip the installer file. For example:
    # unzip greenplum-db-4.3.3.0-PLATFORM.zip
  3. Launch the installer using bash. For example:
    # /bin/bash greenplum-db-4.3.3.0-PLATFORM.bin
  4. The installer will prompt you to accept the Greenplum Database license agreement. Type yes to accept the license agreement.
  5. The installer will prompt you to provide an installation path. Press ENTER to accept the default install path (for example: /usr/local/greenplum-db-4.3.3.0), or enter an absolute path to an install location. You must have write permissions to the location you specify.
  6. The installer installs the Greenplum Database software and creates a greenplum-db symbolic link one directory level above your version-specific Greenplum installation directory. The symbolic link is used to facilitate patch maintenance and upgrades between versions. The installed location is referred to as $GPHOME.
  7. Source the path file from your new 4.3.3 installation. For example:
    $ source /usr/local/greenplum-db-4.3.3.0/greenplum_path.sh
  8. Run the gpseginstall utility to install the 4.3.3 binaries on all the segment hosts specified in the hostfile. For example:
    $ gpseginstall -f hostfile
Upgrade Execution

During upgrade, all client connections to the master will be locked out. Inform all database users of the upgrade and lockout time frame. From this point onward, users should not be allowed on the system until the upgrade is complete.

  1. Source the path file from your old 4.2.x.x installation. For example:
    $ source /usr/local/greenplum-db-4.2.6.3/greenplum_path.sh
  2. (optional but strongly recommended) Back up all databases in your Greenplum Database system using gpcrondump. See the Greenplum Database Administrator Guide for more information on how to do backups using gpcrondump. Make sure to secure your backup files in a location outside of your Greenplum data directories.
  3. If your system has a standby master host configured, remove the standby master from your system configuration. For example:
    $ gpinitstandby -r
  4. Perform a clean shutdown of your current Greenplum Database 4.2.x.x system. For example:
    $ gpstop
  5. Source the path file from your new 4.3.3.0 installation. For example:
    $ source /usr/home/greenplum-db-4.3.3.0/greenplum_path.sh
  6. Update the Greenplum Database environment so it is referencing your new 4.3.3 installation.
    1. For example, update the greenplum-db symbolic link on the master and standby master to point to the new 4.3.3 installation directory. For example (as root):
      # rm -rf /usr/local/greenplum-db
      
      # ln -s /usr/local/greenplum-db-4.3.3.0 /usr/local/greenplum-db
      
      # chown -R gpadmin /usr/local/greenplum-db
    2. Using gpssh, also update the greenplum-db symbolic link on all of your segment hosts. For example (as root):
      # gpssh -f segment_hosts_file
      
      => rm -rf /usr/local/greenplum-db
      
      => ln -s /usr/local/greenplum-db-4.3.3.0 /usr/local/greenplum-db
      
      => chown -R gpadmin /usr/local/greenplum-db
      
      => exit
  7. (optional but recommended) Prior to running the migration, perform a pre-upgrade check to verify that your database is healthy by executing the 4.3.2 version of the gpmigrator utility with the --check-only option. For example:
    $ gpmigrator_mirror --check-only 
       /usr/local/greenplum-db-4.2.6.3 
       /usr/local/greenplum-db-4.3.3.0
  8. As gpadmin, run the 4.3.2 version of the migration utility specifying your old and new GPHOME locations. If your system has mirrors, use gpmigrator_mirror. If your system does not have mirrors, use gpmigrator. For example on a system with mirrors:
    $ su - gpadmin
    $ gpmigrator_mirror /usr/local/greenplum-db-4.2.6.3 
       /usr/local/greenplum-db-4.3.3.0
    Note: If the migration does not complete successfully, contact Customer Support (see Migrating a Greenplum Database That Contains Append-Only Tables).
  9. The migration can take a while to complete. After the migration utility has completed successfully, the Greenplum Database 4.3.2 system will be running and accepting connections.
    Note: After the migration utility has completed, the resynchronization of the mirror segments with the primary segments continues. Even though the system is running, the mirrors are not active until the resynchronization is complete.
Post-Upgrade (on your 4.3.3 system)
  1. If your system had a standby master host configured, reinitialize your standby master using gpinitstandby:
    $ gpinitstandby -s standby_hostname
  2. If your system uses external tables with gpfdist, stop all gpfdist processes on your ETL servers and reinstall gpfdist using the compatible Greenplum Database 4.3.3 Load Tools package. Application Packages are available at Pivotal Network.
  3. Rebuild any custom modules against your 4.3.3 installation (for example, any shared library files for user-defined functions in $GPHOME/lib).
  4. Use the Greenplum Database gppkg utility to install Greenplum Database extensions. If you were previously using any Greenplum Database extensions such as pgcrypto, PL/R, PL/Java, PL/Perl, and PostGIS, download the corresponding packages from Pivotal Network, and install using this utility. See the Greenplum Database Utility Guide 4.3 for usage details.
  5. If you want to utilize the Greenplum Command Center management tool, install the latest Command Center Console and update your environment variable to point to the latest Command Center binaries (source the gpperfmon_path.sh file from your new installation).
    Note: The Greenplum Command Center management tool replaces Greenplum Performance Monitor.

    Command Center Console packages are available from Pivotal Network.

  6. Inform all database users of the completed upgrade. Tell users to update their environment to source the Greenplum Database 4.3.3 installation (if necessary).
