> Two RMNodes for the same NodeId are used in RM sometimes after NM is 
> reconnected. Scheduler and RMContext use different RMNode reference for the 
> same NodeId sometimes after NM is reconnected, which is not correct. 
> Scheduler and RMContext should always use same RMNode reference for the same 
> NodeId.
