(Updated Feb. 5, 2017, 4:40 a.m.)
Review request for hive, Gopal V and Jason Dere.
Changes
-------
Fixed the logic to create a list of ReduceSinkOps,TableScanOps instead of
assuming there is only one such pair in cycle detection logic with hashjoin.
Bugs: HIVE-15808
https://issues.apache.org/jira/browse/HIVE-15808
Repository: hive-git
Description
-------
Remove semijoin branch if it is parallel to a reducer side hash join as the
cycle detection logic does not find a cycle created due to it.
