[jira] [Created] (HIVE-8901) increase retry attempt, interval on metastore database errors

Thejas M Nair created HIVE-8901:
-----------------------------------

             Summary: increase retry attempt, interval on metastore database errors
                 Key: HIVE-8901
                 URL: https://issues.apache.org/jira/browse/HIVE-8901
             Project: Hive
          Issue Type: Bug
            Reporter: Thejas M Nair
            Assignee: Thejas M Nair
             Fix For: 0.15.0


The current defaults of hive.hmshandler.retry.attempts=1 and hive.hmshandler.retry.interval=1s are very small. In some cases one retry is not sufficient for successful command execution.
 
I have seen cases, specially after metastore being idle for sometime, when it takes 2 attempts for the db action to succeed. In this case, it as a Communications link failure/connection lost error.
