Description
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 reset 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:
