(Updated Aug. 29, 2017, 7:28 p.m.)
Review request for hive, Gopal V and Jason Dere.
Changes
-------
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
https://issues.apache.org/jira/browse/HIVE-17323
Repository: hive-git
Description
-------
HIVE-16260 allows removal of parallel edges of semijoin with mapjoins.
https://issues.apache.org/jira/browse/HIVE-16260
However, it should also consider dynamic partition pruning edge like semijoin
without removing it while traversing the query tree.
