Gunther Hagleitner created HIVE-10005:
-----------------------------------------

             Summary: remove some unnecessary branches from the inner loop
                 Key: HIVE-10005
                 URL: https://issues.apache.org/jira/browse/HIVE-10005
             Project: Hive
          Issue Type: Bug
            Reporter: Gunther Hagleitner
            Assignee: Gunther Hagleitner
         Attachments: HIVE-10005.1.patch

Operator.forward is doing too much. There's no reason to do the "done" checking per row and update it inline. It's much more efficient to just do that when the event that completes an operator happens.
