---------------------------------
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.
