Registering PXF JAR Dependencies

A newer version of this documentation is available. Use the version menu above to view the most up-to-date release of the Greenplum 6.x documentation.

You use PXF to access data stored on external systems. Depending upon the external data store, this access may require that you install and/or configure additional components or services for the external data store.

PXF depends on JAR files and other configuration information provided by these additional components. The $GPHOME/pxf/conf/pxf-private.classpath file identifies PXF internal JAR dependencies. In most cases, PXF manages the pxf-private.classpath file, adding entries as necessary based on the connectors that you use.

Should you need to add an additional JAR dependency for PXF, for example a JDBC driver JAR file, you must log in to the Greenplum Database master host, copy the JAR file to the PXF user configuration runtime library directory ($PXF_CONF/lib), sync the PXF configuration to the Greenplum Database cluster, and then restart PXF on each segment host. For example:

$ ssh gpadmin@<gpmaster>
gpadmin@gpmaster$ cp new_dependent_jar.jar $PXF_CONF/lib/
gpadmin@gpmaster$ $GPHOME/pxf/bin/pxf cluster sync
gpadmin@gpmaster$ $GPHOME/pxf/bin/pxf cluster stop
gpadmin@gpmaster$ $GPHOME/pxf/bin/pxf cluster start
