Zhijie Shen commented on YARN-2779: ----------------------------------- I've verified it in a secure cluster, and SystemMetricsPublisher works fine with kerberos directly. > SystemMetricsPublisher can use Kerberos directly instead of timeline DT > ----------------------------------------------------------------------- > > Key: YARN-2779 > URL: https://issues.apache.org/jira/browse/YARN-2779 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager, timelineserver > Affects Versions: 2.6.0 > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Priority: Critical > Attachments: YARN-2779.1.patch > > > SystemMetricsPublisher is going to grab a timeline DT in secure mode as well. > The timeline DT will expiry after 24h. No DT renewer will handle renewing > work for SystemMetricsPublisher, but this has to been handled by itself. In > addition, SystemMetricsPublisher should cancel the timeline DT when it is > stopped, too. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
