> improve node decommission latency in RM.
> Currently the node decommission only happened after RM received nodeHeartbeat
> from the Node Manager. The node heartbeat interval is configurable. The
> default value is 1 second.
> It will be better to do the decommission during RM Refresh(NodesListManager)
> instead of nodeHeartbeat(ResourceTrackerService).
