Gunther Hagleitner commented on HIVE-18875:
-------------------------------------------
I've also read more of the code in ConvertJoinMapJoin. You've introduced a
check that the column lists are the same right before an existing call to
"checkColEquality". That seems mostly redundant, except that you turned the
sort col step from non-strict to strict. Why is any of this code needed?
