      rmContext.getDispatcher().register(NodeEventType.class,
          new TajoResourceManager.WorkerEventDispatcher(rmContext));

      barrier = new Semaphore(0);
      scheduler = new MySimpleScheduler(rmContext, barrier);
      addService(scheduler);
      rmContext.getDispatcher().register(SchedulerEventType.class, scheduler);
