> TestJobHistoryEvents and TestJobHistoryParsing are not properly waiting for MRApp to
finish.  Currently they are polling the service state looking for Service.STATE.STOPPED, but
the service can appear to be in that state *before* it is fully stopped.  This causes tests
to finish with MRApp threads still in-flight, and those threads can conflict with subsequent
tests when they collide in the filesystem.
