Vineet Garg updated HIVE-16838:
-------------------------------
Attachment: HIVE-16838.1.patch
cc [~ashutoshc] This is a preliminary patch which eliminates un-necessary join
with outer query for non-equi correlated predicates (same as equi correlated
predicates).
It still has issues which I am working on. Uploading it to run tests to see
failure.
> Improve plans for subqueries with non-equi co-related predicates
