-----------------------------
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

Its better we send 0 as CPU usage rather than sending a negative values in
heartbeats eventhough its happening in only first few heartbeats.
