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

             Summary: The default value for 
yarn.nodemanager.container-metrics.period-ms should not be -1.
                 Key: YARN-3628
                 URL: https://issues.apache.org/jira/browse/YARN-3628
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: zhihai xu
            Assignee: zhihai xu
            Priority: Minor


The default value for yarn.nodemanager.container-metrics.period-ms should not 
be -1.
The current default value for yarn.nodemanager.container-metrics.period-ms is 
-1 and the default value  for yarn.nodemanager.container-metrics.enable is 
true. So the empty content is shown for the active container metrics until it 
is finished.
flushOnPeriod is always false if flushPeriodMs is -1,
the content will only be shown when the container is finished.
{code}
    if (finished || flushOnPeriod) {
      registry.snapshot(collector.addRecord(registry.info()), all);
    }
{code}
