> Key: YARN-5709
> URL: https://issues.apache.org/jira/browse/YARN-5709
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.8.0
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla
> Priority: Blocker
> Attachments: yarn-5709-wip.2.patch, yarn-5709.1.patch,

>
> 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.
