Rui Li commented on HIVE-8616:
------------------------------

Hi [~ssatish], forgive my ignorance, but why do we need two map joins if the 
join key is the same for the three tables? I think MR will handle this join 
with only one map join, right?

> convert joinOp to MapJoinOp and generate MapWorks only [Spark Branch]
