> 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.
