Varun Saxena commented on YARN-7662:
------------------------------------
[~rohithsharma], thanks for the latest patch.
As we have already released ATSv2 and the addresses depend on
yarn.timeline-service.bind-host, to maintain backward compatibility, we should
fall back to it if yarn.timeline-service.reader/collector.bind-host is not set
> [Atsv2] Define new set of configurations for reader and collectors to bind.

> While starting Timeline Reader in secure mode, login happens using
> timeline.service.address even though timeline.service.bindhost is configured
> with 0.0.0.0. This causes exact principal name that matches address name to
> be present in keytabs.
> It is always better to login using getLocalHost that gives machine hostname
> which is configured in /etc/hosts unlike NodeManager does in serviceStart.
> And timeline.service.address is not required in non-secure mode, so its
> better to keep consistent in secure and non-secure mode
