Karthik Kambatla updated YARN-5709:
-----------------------------------
Attachment: yarn-5709.2.patch
Patch v2 should take care of javadoc, checkstyle warnings, and unit test
failures.
Only TestRMHA and TestZKRMStateStore had real failures, others were all passing
for me locally. Let us see how the next run goes.
> Cleanup leader election configs and pluggability

> Affects Versions: 2.8.0
> Reporter: Karthik Kambatla

> While reviewing YARN-5677 and YARN-5694, I noticed we could make the
> curator-based election code cleaner. It is nicer to get this fixed in 2.8
> before we ship it, but this can be done at a later time as well.
> # By EmbeddedElector, we meant it was running as part of the RM daemon. Since
> the Curator-based elector is also running embedded, I feel the code should be
> checking for {{!curatorBased}} instead of {{isEmbeddedElector}}
> # {{LeaderElectorService}} should probably be named
> {{CuratorBasedEmbeddedElectorService}} or some such.
> # The code that initializes the elector should be at the same place
> irrespective of whether it is curator-based or not.
> # We seem to be caching the CuratorFramework instance in RM. It makes more
> sense for it to be in RMContext. If others are okay with it, we might even be
> better of having {{RMContext#getCurator()}} method to lazily create the
> curator framework and then cache it.
