Sergio Peña commented on HIVE-14307:
------------------------------------

I'm moving this JIRA out of 2.1.1 release as it is not a blocker nor critical for a 2.1.1
RC version. Feel free to commit it to branch 2.1 if the patch is ready before the release.

> This extends HIVE-13096 so the heuristic can take into account top operators that produce
large number of rows. In the future, we should choose the side based on total latency for
the input.
