SP1.
Hive
- CDPD-88944: New configuration available to disable the Partition Management Task
-
Previous behavior:
- Disable the PartitionManagementTask, which put a heavy load on the
Hive Metastore when managing a large number of tables and partitions. Users had a tedious
workaround by providing a pattern through
metastore.partition.management.database.pattern or
metastore.partition.management.table.pattern.
-
New behavior:
- You can now set the
metastore.partition.management.task.frequency configuration to 0 to
disable the partition management task cluster-wide.

Apache Jira: HIVE-25324
Ozone
- Removal of the ozone.snapshot.ordered.deletion.enabled configuration
property
-
Previous behavior:
- Previously, users could configure
ozone.snapshot.ordered.deletion.enabled property to enforce ordered
snapshot deletion as a workaround for a race condition issue during snapshot garbage
collection.
-
New behavior:
- Now, because the underlying race condition bug in snapshot garbage
collection has been resolved, the ozone.snapshot.ordered.deletion.enabled
property has been removed, is no longer needed, and has no effect if configured.
