Subject [jira] [Updated] (YARN-7660) NM node resource should be updated through heartbeat when rmadmin updateNodeResource execute successfully
Date Fri, 15 Dec 2017 10:36:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-7660?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
