Zoltan Haindrich commented on HIVE-20576:
-----------------------------------------
seems like having the following 2 options enable at the same time may lead to
incorrect results:
* {{hive.auto.convert.join}}
* {{hive.transpose.aggr.join}}
> Fix incorrect results in multiMapJoin2 when hive.transpose.aggr.join is
> enabled
