             Summary: SystemMetricsPublisher needs to renew and cancel timeline 
DT too
                 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

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.
