Ravi Prakash commented on YARN-4832:
------------------------------------

Thanks for all your work Junping and Jian! Should we also modify the limits set in [ContainersMonitorImpl.maxPmemAllottedForContainers|https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/monitor/ContainersMonitorImpl.java#L76]
etc. also?

> Now, if we execute CLI to update node (single or multiple) resource in RM side, NM will
not receive any notification. It doesn't affect resource scheduling but will make resource
usage metrics reported by NM a bit weird. We should sync up new resource between RM and NM.
