Jonathan Eagles commented on YARN-3144:
---------------------------------------
While I agree that it eventually will be a necessary serviceat all times. In
the case of a dual history writer in the transition from Mapreduce history and
timeline, you are increasing instability for jobs. This allows users to
evaluate the timeline history server without introducing instability.

> Posting events to the timeline server is best-effort. However, getting the
> delegation tokens from the timeline server will kill the job. This patch adds
> a configuration to make get delegation token operations "best-effort".
