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.
