Gunther Hagleitner commented on HIVE-18875:
-------------------------------------------
If I read this right, then you're new check in ConvertJoinMapjoin basically
makes sure that there is no projection in between gby and join that would alter
bucketing or sorting. That is exactly what op traits are for - why can't we use
that in this case?
