[jira] [Commented] (YARN-4308) ContainersAggregated CPU resource
utilization reports negative usage in first few heartbeats
[ https://issues.apache.org/jira/browse/YARN-4308?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15309062#comment-15309062 ]
Daniel Templeton commented on YARN-4308:
----------------------------------------
[~sunilg], I don't think just fixing the existing tests to not break with the change is enough. I would prefer it if we could test both what happens when the {{cpuUsagePercent}} is 0 and when it's -1. Right now we're not testing that the -1's are skipped correctly.

> NodeManager reports ContainerAggregated CPU resource utilization as -ve value in first few heartbeats cycles. I added a new debug print and received below values from heartbeats.
> {noformat}
> INFO org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainersMonitorImpl: ContainersResource Utilization : CpuTrackerUsagePercent : -1.0
> INFO org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainersMonitorImpl:ContainersResource Utilization : CpuTrackerUsagePercent : 198.94598
> {noformat}
> Its better we send 0 as CPU usage rather than sending a negative values in heartbeats eventhough its happening in only first few heartbeats.
