> Currently, we move rmDispatcher out of ActiveService. But we still register
> the Event dispatcher, such as schedulerDispatcher, RMAppEventDispatcher when
> we initiate the ActiveService.
> Almost every time when we transit RM from Active to Standby, we need to
> initiate the ActiveService. That means we will register the same event
> Dispatcher which will cause the same event will be handled several times.
