------------------------------------
[~kasha], we have a test {{TestAppManager#testRMAppRetireZeroSetting}} to
verify this case.
So closing this JIRA as invalid.
Kindly reopen if you disagree.
> Provide a way to store only running applications in the state store

> Key: YARN-3643
> URL: https://issues.apache.org/jira/browse/YARN-3643
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.7.0
> Reporter: Karthik Kambatla
> Assignee: Varun Saxena
>
> Today, we have a config that determines the number of applications that can
> be stored in the state-store. Since there is no easy way to figure out the
> maximum number of running applications at any point in time, users are forced
> to use a conservative estimate. Our default ends up being even more
> conservative.
> It would be nice to allow storing all running applications with a
> conservative upper bound for it. This should allow for shorter recovery times
> in most deployments.
