Bh V S Kamesh commented on MAPREDUCE-3585:
------------------------------------------
If the NMs have been configured to use static ports, we can store the lost NMs
information by their NodeID and hence RM can detect the NM's comeback.
I *think* there should be a mechanism, even if the NMs have been configured to
use ephemeral ports.
> RM unable to detect NMs restart
