Daniel Templeton resolved YARN-4800. ------------------------------------ Resolution: Duplicate > ContainerMetrics drops records > ------------------------------ > > Key: YARN-4800 > URL: https://issues.apache.org/jira/browse/YARN-4800 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.9.0 > Reporter: Daniel Templeton > Assignee: Daniel Templeton > > The metrics2 system was implemented to deal with persistent sources. > {{ContainerMetrics}} is an ephemeral source, and so it causes problems. > Specifically, the {{ContainerMetrics}} only reports metrics once after the > container has been stopped. This behavior is a problem because the metrics2 > system can ask sources for reports that will be quietly dropped by the sinks > that care. (It's a metrics2 feature, not a bug.) If that final report is > silently dropped, it's lost, because the {{ContainerMetrics}} won't report > anything else ever anymore. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
