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

             Summary: Runtime rowcount calculation is incorrect in vectorized executions
                 Key: HIVE-21288
                 URL: https://issues.apache.org/jira/browse/HIVE-21288
             Project: Hive
          Issue Type: Bug
            Reporter: Zoltan Haindrich
            Assignee: Zoltan Haindrich



before HIVE-18908; there was a baseForward (non vectorized) and vectorForward (vectorized); and both of them have accounted for the number of rows correctly - after HIVE-18908 this have changed to count vectorized batches in case of vectorized execution.
