> 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.
