Should use equals when compare Resource in RMNodeImpl#ReconnectNodeTransition to avoid unnecessary NodeResourceUpdateSchedulerEvent.
The current code use != to compare Resource totalCapability, which will compare reference not the real value in Resource. So we should use equals to compare Resource.
