             Summary: We should provide better error message while constraints with duplicate names are created
                 Key: HIVE-13608
                 URL: https://issues.apache.org/jira/browse/HIVE-13608
             Project: Hive
          Issue Type: Bug
            Reporter: Hari Sankar Sivarama Subramaniyan
            Assignee: Hari Sankar Sivarama Subramaniyan

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:For direct MetaStore DB connections, we don't support retries at the client level.)
{code}

In the above case, it seems like useful error message is lost. It looks like a  generic problem with metastore server/client exception handling and message propagation. Seems like exception parsing logic of RetryingMetaStoreClient::invoke() needs to be updated.
