Description

As per the discussion in YARN-3971 the we should be setting the service state to STARTED only after serviceStart()
Currently AbstractService#start() is set

 
     if (stateModel.enterState(STATE.STARTED) != STATE.STARTED) {
        try {
          startTime = System.currentTimeMillis();
          serviceStart();
..
 }

enterState sets the service state to proposed state. So in service.getServiceState in serviceStart() will return STARTED .
