Review request for hive and Jason Dere.
Bugs: HIVE-16947
https://issues.apache.org/jira/browse/HIVE-16947
Repository: hive-git
Description
-------
Typically a semijoin branch and a mapjoin may create a cycle when on same
operator tree. This is already handled, however, a semijoin branch can serve
more than one filters and the cycle detection logic currently only handles the
1st one causing cycles preventing the queries from running.
