Yang Wang updated YARN-7660:
----------------------------
Description:
When yarn rmadmin -updateNodeResource is used to update node resource, and
execute successfully. The new capability should be sent to NM througn RM-NM
heartbeat.
1. NM jmx metrics need to be updated
2. NM cgroup quota need to be updated
was:
{code:title=NodeManagerMetrics.java}
public void addResource(Resource res) {
availableMB = availableMB + res.getMemorySize();
availableGB.incr((int)Math.floor(availableMB/1024d));
availableVCores.incr(res.getVirtualCores());
}
{code}
When the node resource was updated through RM-NM heartbeat, the NM metric will
get wrong value.
The root cause of this issue is that new resource has been added to
availableMB, so not needed to increase for availableGB again.
> NM node resource should be updated through heartbeat when rmadmin
> updateNodeResource execute successfully
