> Affects Versions: 2.7.0

> 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.
