> 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.
