Jonathan Eagles commented on MAPREDUCE-3494:
--------------------------------------------
A side-effect of this is that NMs using static (non-ephemeral) ports are unable
to rejoin until after the expiry period
(yarn.resourcemanager.nm.liveness-monitor.expiry-interval-ms default is 10
minutes!).
> The RM should handle the graceful shutdown of the NM.
