Description

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.
