-------------------------------------------------------

             Summary: Hive RetryHMSHandler should be retrying the metastore operation in case
of NucleusException
                 Key: HIVE-8766
                 URL: https://issues.apache.org/jira/browse/HIVE-8766
             Project: Hive
          Issue Type: Bug
            Reporter: Hari Sankar Sivarama Subramaniyan
            Assignee: Hari Sankar Sivarama Subramaniyan


When we have Metastore operations and the Metastore Database is heavily loaded or takes a
long time to respond, we might run into NucleusExceptions as shown in the below stacktrace.
In the below scenario, the MetastoreDB is SQL Server and the SQLServer is configured to timeout
and terminate with a connection rest after x seconds if it doesnt return a ResultSet. While
this needs configuration change at the Metastore DB side, we need to make sure that in such
cases the HMS Retrying mechanism should not provide a rigid rule to fail such hive queries.
The proposed fix would be allow retries when we hit a Nucleus Exception as shown below:
