Review request for Ambari, Alejandro Fernandez and Jonathan Hurley.


Bugs: AMBARI-10065
    https://issues.apache.org/jira/browse/AMBARI-10065


Repository: ambari


Description
-------

During analysis of a 400 node cluster, the ActionScheduler is loading too many 
stages, when it already has a handle to the correct stage.  The entire Request 
is not needed, when the code only checks the exclusive flag.
