Summary: MaterializationsRebuildLockCleanerTask never cleans the
abandoned MV Rebuild Lock entries from MATERIALIZATION_REBUILD_LOCKS table.
Key: HIVE-28563
URL: https://issues.apache.org/jira/browse/HIVE-28563
Project: Hive
Issue Type: Bug
Security Level: Public (Viewable by anyone)
Components: Materialized views
Reporter: Dayakar M
Assignee: Dayakar M
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.
