>
> 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.
