             Summary: YARN theme and 'yarn.nodemanager.resource.cpu-vcores' calculation updates
                 Key: AMBARI-11003
                 URL: https://issues.apache.org/jira/browse/AMBARI-11003

          Issue Type: Task
          Components: contrib
    Affects Versions: 2.1.0
            Reporter: Srimanth Gunturi
            Assignee: Srimanth Gunturi

         Attachments: choice1.png

YARNs theme should be updated as shown in attached screenshot.

Also, the calculation for {{yarn.nodemanager.resource.cpu-vcores}} should be dependent on {{yarn.nodemanager.resource.percentage-physical-cpu-limit}} and the #-physical-cores on NodeManager.
{noformat}
minimum = 1
maximum = 2 * #-physical-cores
recommended = max(1, floor(#-physical-cores * yarn.nodemanager.resource.percentage-physical-cpu-limit))
{noformat}

This new value will be the max of {{yarn.scheduler.minimum-allocation-vcores}} and {{yarn.scheduler.maximum-allocation-vcores}}.
