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

             Summary: Eliminate unnecessary MapJoin restriction in HIVE-11394
                 Key: HIVE-14981
                 URL: https://issues.apache.org/jira/browse/HIVE-14981
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 2.2.0
            Reporter: Matt McCline
            Assignee: Matt McCline
            Priority: Critical
             Fix For: 2.2.0


No Empty Key restriction for Native Vector MapJoin added with HIVE-11394 is unnecessary.  It caused Llap orc_llap.q test to timeout on Hive QA because regular VectorMapJoinOperator is too slow.
