Szehon Ho commented on HIVE-8536:
---------------------------------
Got it.
[~csun] may correct me if wrong, but I believe the MapWork needs to be
connected if they represent tables for the same mapjoin in this way: MapWork
(small) --> MapWork (big). It's the way SparkMapJoinResolver may know to split
them.
