Janos Kovacs created HIVE-26145: ----------------------------------- Summary: Disable notification cleaner if interval is zero Key: HIVE-26145 URL: https://issues.apache.org/jira/browse/HIVE-26145 Project: Hive Issue Type: Sub-task Components: Metastore Reporter: Janos Kovacs Assignee: Janos Kovacs
Many of the housekeeping/background tasks can be turned off in case of having multiple instances running parallel. Some are controlled via the housekeeping node configuration, others are not started if their frequency is set to zero. The DB-Notification cleaner unfortunately doesn't have this functionality which makes all instances to race for the lock on the backend HMS database. Goal is to add change to be able to turn cleaner off in case if there are multiple instances running (be able to bound it to the housekeeping instance). -- This message was sent by Atlassian Jira (v8.20.1#820001)
