-----------------------------------
[~Zhongkai], Perhaps the fix for YARN-5117 might be relevant here.
> Issue of CPU usage of containers
> --------------------------------
>
> Key: YARN-5179
> URL: https://issues.apache.org/jira/browse/YARN-5179
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.7.0
> Environment: Both on Windows and Linux
> Reporter: Zhongkai Mi
>
> // Multiply by 1000 to avoid losing data when converting to int
> int milliVcoresUsed = (int) (cpuUsageTotalCoresPercentage * 1000
> * maxVCoresAllottedForContainers /nodeCpuPercentageForYARN);
> This formula will not get right CPU usage based vcore if vcores != physical cores.
