Sunil G created YARN-4308: ----------------------------- Summary: 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
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
