Behavioral Changes in Cloudera Runtime 7.3.1

Summary:

Change in the way compaction initiator and cleaner threads are handled

Previous behavior:

The compaction initiator and cleaner threads are enabled and disabled by setting the hive.compactor.initiator.on property to 'true' or 'false'.

New behavior:

A new property hive.compactor.cleaner.on is introduced that allows you to selectively enable or disable the cleaner thread.

This property is not listed and is set to 'false' by default. Add the property to Hive Metastore Server Advanced Configuration Snippet (Safety Valve) for hive-site.xml in Cloudera Manager to have the same out-of-the-box experience as in the previous version.

Also, ensure that you set the property to 'true' for the compactor to run on the HMS instance.
