Hari Sankar Sivarama Subramaniyan updated HIVE-8766: ---------------------------------------------------- Attachment: HIVE-8766.2.patch Moving NucleusException to import as per [~hagleitn] 's comment. > 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 > Components: Metastore > Reporter: Hari Sankar Sivarama Subramaniyan > Assignee: Hari Sankar Sivarama Subramaniyan > Fix For: 0.14.0 > > Attachments: HIVE-8766.1.patch, HIVE-8766.2.patch > > > 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: > {noformat} > 2014-11-04 06:40:03,208 ERROR bonecp.ConnectionHandle > (ConnectionHandle.java:markPossiblyBroken(388)) - Database access problem. > Killing off this connection and all remaining connections in the connection > pool.
