[jira] [Created] (HIVE-14946) Optimizations

Eugene Koifman created HIVE-14946:
-------------------------------------

             Summary: Optimizations
                 Key: HIVE-14946
                 URL: https://issues.apache.org/jira/browse/HIVE-14946
             Project: Hive
          Issue Type: Sub-task
          Components: Query Planning, Transactions
            Reporter: Eugene Koifman


For example, if there is only WHEN NOT MATCHED clause, the base generating expression can be an INNER JOIN

Generally, we should make sure the optimizer is able to work with the plan for Merge statement
