(Updated Aug. 30, 2017, 2:21 a.m.)
Review request for hive, Gopal V and Jason Dere.
Changes
-------
Redid the code to track the parallel semijoin edges when it encounters a
MapJoinOperator in small table side.
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.
