PXF Upgrade and Migration
When you upgrade your Greenplum Database system, you must perform some additional steps in order to bring your PXF configuration up to date.
There are three possible scenarios:
- Upgrading PXF after migrating from Greenplum Database 5.x. If you were previously using the
gphdfs
external table protocol to access data stored in Hadoop, you must migrate your gphdfs external tables to use PXF instead, since Greenplum Database version 6 removes support for thegphdfs
protocol. - Upgrading PXF after upgrading Greenplum Database from a previous 6.x version. Note that different steps are outlined based on your PXF installation source: a manually installed
rpm
ordeb
package downloaded from Tanzu Network, or the version included with Greenplum Database installer. - If you are upgrading a PXF
rpm
ordeb
installation outside of a Greenplum Database upgrade, refer to the PXF Documentation.
