             Summary: Output vectorized GROUP BY with only primitive aggregate fields as columns so downstream operators will be vectorized
                 Key: HIVE-7537
                 URL: https://issues.apache.org/jira/browse/HIVE-7537
             Project: Hive
          Issue Type: Sub-task
            Reporter: Matt McCline
            Assignee: Matt McCline


When under Tez engine, see if the VectorGroupByOperator aggregrates are all primitive (e.g. sum) and batch the output rows into a VectorizedRowBatch.  And, vectorize downstream operators.
