-------------------------------
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}
