------------------------------------
[~asuresh]
While trying to reproduce this issue, seeing some values for milliVcoresUsed
variable in recordUsage() method of ContainersMonitorImpl.java class. Also, I
am seeing major code changes as part of
https://issues.apache.org/jira/browse/YARN-4597. Hence, thought of confirming
with you on this jira. Is this still valid?
Kindly let me know on how to proceed with this.
> 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.
