Subject [jira] [Resolved] (YARN-2779) SystemMetricsPublisher needs to renew and cancel timeline DT too
Date Thu, 30 Oct 2014 21:57:34 GMT

Vinod Kumar Vavilapalli resolved YARN-2779.
    Resolution: Invalid

This doesn't make any sense.

RM can simply use kerberos based auth to talk to Timeline service. It doesn't need tokens
at all.

Closing this as invalid, reopen if you disagree.

> 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.
