Known Issues and Workarounds

Issue

There is a potential memory leak with specific queries, affected by gpperfmon engine. If you use queries on huge tables with UDFs, which generate inner per-tuple queries, you may expirience significant RAM consumption, and even get OOM errors. The example is view information_schema.columns, that can cause memory leak when selected upon large system catalog. The solution may be to switch off metrics monitoring (operation requires restarting cluster):

Workaround

  • Remove gpadcc from shared_preload_libraries, e.g.:

    gpconfig -c shared_preload_libraries -v ""

  • Switch off the following parameters:

    gpconfig -c gp_enable_gpperfmon -v off
gpconfig -c adcc.explain_log_verbose -v off
gpconfig -c adcc.explain_log_analyze -v off

  • Restart your cluster:

    gpstop -a -M fast
gpstart a

Keep in mind, that WA does not disable ADCC UI and Arenadata DB Bbackup Manager will be enabled.

Issue

During installation of encryption module, you will be encountered with ERROR: Encryption library was not found in /var/lib/pxf/lib/ directory

Workaround

Copy necessary library from /usr/lib/pxf/lib/:

cp /usr/lib/pxf/lib/encryption-1.0.0-exec.jar /var/lib/pxf/lib/encryption-1.0.0-exec.jar

Issue

If you upgrade your cluster to 6.22.1_arenadata40 with installed ADCC with ADCC-LDAP switched on, please note that newer ADB server will not be registered in ADCC and its version in ADCC Information remaines as older ADB server. It doesn’t affect any functionality but should be kept in mind.

Workaround

  1. Uninstall ADCC before upgrading cluster to 6.22.1_arenadata40.
  2. Run Upgrade.
  3. Reinstall ADCC after upgrade.

Issue

If you upgrade your cluster to 6.22.1_arenadata40, please note that during this process table arenadata_toolkit.db_files_history will be recreated with partitions/compression and data will be reloaded to a new one. Keep in mind that this process may take quite a lot of time in case your table is huge.

Workaround

If you don’t want to include migration of arenadata_toolkit.db_files_history into upgrade process, please rename table db_files_history before the upgrade, and rename it back after upgrade, e.g.:

  1. alter table arenadata_toolkit.db_files_history rename to db_files_history_skip;
  2. Run ADB Cluster Upgrade Action from ADCM and wait for successful upgrade.
  3. alter table arenadata_toolkit.db_files_history_skip rename to db_files_history;
