[jira] [Created] (HIVE-16208) Vectorization: ProcessingModeHashAggregate::sumBatchSize is never reset

Gopal V created HIVE-16208:
------------------------------

             Summary: Vectorization: ProcessingModeHashAggregate::sumBatchSize is never reset
                 Key: HIVE-16208
                 URL: https://issues.apache.org/jira/browse/HIVE-16208
             Project: Hive
          Issue Type: Bug
            Reporter: Gopal V


When processing >2x the hash-table size in the vectorized group-by, the check for fall-back to streaming is wrong because {{sumBatchSize*minReduction}} is not modified by a partial flush or a full flush.
