> Total resource count mistake:
> NodeRemovedSchedulerEvent in ReconnectNodeTransition will reduce the newNode.getTotalCapability()
in Multi-thread model. Since the RMNode and scheduler in different queue. So it cannot guarantee
the remove-update-add operation in sequence. Usually the total resource will reduce the newNode.getTotalCapability()
when handling NodeRemovedSchedulerEvent.
