Description
HIVE-17767 optimized plan to not generate value generator (i.e. an extra join with outer query to fetch correlated columns) for EQUAL and NOT EQUAL predicates e.g.
select * from src b where b.key in (select key from src a where b.value <> a.value)
This should be improved and implemented for rest of the predicates e.g. LESS THAN etc
