Dayakar M updated HIVE-28563:
-----------------------------
Description:
This is a followup Jira for HIVE-28416
MaterializationsRebuildLockCleanerTask never cleans the abandoned MV Rebuild
Lock entries from MATERIALIZATION_REBUILD_LOCKS table.
As a part MaterializationsRebuildLockCleanerTask, before clearing the entries
it checks whether the last heartbeat time for this lock entry is lesser than
the (current time - hive transaction timeout) but the
MaterializationRebuildLockHeartbeater heartbeats every (hive transaction
timeout/2) so above condition will never meet and it won't clean the entries.
