Change subject: IMPALA-1473: Incorrect cardinality in exec summary for exchange ...................................................................... IMPALA-1473: Incorrect cardinality in exec summary for exchange When there is a merging exchange with a limit, we may copy rows into the output batch beyond the limit. In this case, we currently update the output batch's size to reflect the limit, but we also need to update ExecNode::num_rows_returned_ or the exec summary may show that the exchange node returned more rows than it really did.
