Sunil G commented on YARN-4308: ------------------------------- Hi [~templedf] [~Naganarasimha Garla] also had a same concern. And earlier i tried to explain with this [comment.|https://issues.apache.org/jira/browse/YARN-4308?focusedCommentId=15258302&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15258302]. With {{MockResourceCalculatorProcessTree#getCpuUsagePercent}}, I am overriding the default CPU usage from -1 to 0. If I am not overloading, then this will always be skipped in {{ContainreMonitor}}. Actual;y existing tests were covering this scenario already. Do you see whether we need one more test for same?. Pls help to share your thoughts. > ContainersAggregated CPU resource utilization reports negative usage in first > few heartbeats > -------------------------------------------------------------------------------------------- > > Key: YARN-4308 > URL: https://issues.apache.org/jira/browse/YARN-4308 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 2.7.1 > Reporter: Sunil G > Assignee: Sunil G > Attachments: 0001-YARN-4308.patch, 0002-YARN-4308.patch, > 0003-YARN-4308.patch, 0004-YARN-4308.patch > > > NodeManager reports ContainerAggregated CPU resource utilization as -ve value > in first few heartbeats cycles.
