Vikram Dixit K commented on HIVE-13619:
---------------------------------------
Yes. The method is named findSingleUpstreamOperatorJoinAccounted. We are
expecting only one instance of the operator type to be returned. It is not
trying to find one specific operator in the list.
> Bucket map join plan is incorrect
