Devaraj K commented on MAPREDUCE-3070:
--------------------------------------
Here one more problem is that, when the duplicate registration comes it is
adding up the resource to cluster resource in the capacity scheduler without
checking whether the nodemanager resource is already added or not.
> NM not able to register with RM after NM restart
