Review request for hive, Gopal V and Jason Dere.


Updated the test to work with and without semijoin reduction for better comparison.
The result is different because it is working on a smaller table created with only 40 rows.

Bugs: HIVE-17323

Repository: hive-git


HIVE-16260 allows removal of parallel edges of semijoin with mapjoins.
However, it should also consider dynamic partition pruning edge like semijoin without removing
it while traversing the query tree.

Diffs (updated)
