Yang Wang created YARN-7661:
-------------------------------
Summary: NodeManager metrics return wrong value after update node
resource
Key: YARN-7661
URL: https://issues.apache.org/jira/browse/YARN-7661
Project: Hadoop YARN
Issue Type: Bug
Reporter: Yang Wang
{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.
