Review request for hive, Gopal V, Jason Dere, and Siddharth Seth.
Bugs: HIVE-16282
https://issues.apache.org/jira/browse/HIVE-16282
Repository: hive-git
Description
-------
Currently all reducers have slow start meaning, the mappers get preference in
scheduling. However, incase of semijoin reductions, the reducer of semijoin
branch should get priority before the mapper to which it feeds in.
