Learn about the change in certain functionality of Hive that has resulted in a change in
behavior from the previously released version to this version of Cloudera Runtime.
- 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.
