Sangjin Lee updated YARN-4356:
------------------------------
Attachment: YARN-4356-feature-YARN-2928.002.patch
Posted patch v.2. This should be a reasonably complete patch.
Changes since v.1:
- added TIMELINE_SERVICE_VERSION config per YARN-3623
- removed MAPREDUCE_JOB_NEW_TIMELINE_SERVICE_ENABLED and had MR use the
timeline service version
- removed the command line flag in distributed shell, and had it rely on the
timeline service version instead
- clarified the purpose of SYSTEM_METRICS_PUBLISHER_ENABLED to be about
controlling the subfeature of publishing the system events/metrics under
timeline service v.2
- clarified the purpose of RM_SYSTEM_METRICS_PUBLISHER_ENABLED to be about
controlling the subfeature of publishing the system events/metrics by RM under
timeline service v.1
- added checks for the timeline v.2 config in the timeline collector service
and the reader server
- fixed a NPE in NodeStatusUpdaterImpl.updateTimelineClientsAddress()
> ensure the timeline service v.2 is disabled cleanly and has no impact when
> it's turned off

> For us to be able to merge the first milestone drop to trunk, we want to
> ensure that once disabled the timeline service v.2 has no impact from the
> server side to the client side. If the timeline service is not enabled, no
> action should be done. If v.1 is enabled but not v.2, v.1 should behave the
> same as it does before the merge.
