> I had 6 nodes in a cluster with 2 NMs stopped. Then I put a host into YARN's {{yarn.resourcemanager.nodes.exclude-path}}.
After running {{yarn rmadmin -refreshNodes}}, RM's JMX correctly showed decommissioned node
count:
> {noformat}
> "NumActiveNMs" : 3,
> "NumDecommissionedNMs" : 1,
> "NumLostNMs" : 2,
> "NumUnhealthyNMs" : 0,
> "NumRebootedNMs" : 0
> {noformat}
> After restarting RM, the counts were shown as below in JMX.
> {noformat}
> "NumActiveNMs" : 3,
> "NumDecommissionedNMs" : 0,
> "NumLostNMs" : 0,
> "NumUnhealthyNMs" : 0,
> "NumRebootedNMs" : 0
> {noformat}
> Notice that the lost and decommissioned NM counts are both 0.
