Gunther Hagleitner commented on HIVE-18875:
-------------------------------------------
I don't think it makes sense to have code in the join operator that checks
whether the parent is a group by operator. It either is the correct logic to
close parents or it isn't, doing it conditionally per "parent operator" will
either leave things half fixed now or break things in future.
