> 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}}.
