Gunther Hagleitner commented on HIVE-18875:
-------------------------------------------
The join operator should not have to check whether the parent is a group by -
that seems brittle. Can we always force the logic to close other branches to
flush out remaining records? If we introduce any other blocking operators the
same logic has to apply, right?
