    [ https://issues.apache.org/jira/browse/YARN-3643?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14615081#comment-14615081

Varun Saxena commented on YARN-3643:

[~kasha], we have a test {{TestAppManager#testRMAppRetireZeroSetting}} to verify this case.
So closing this JIRA as invalid.

Kindly reopen if you disagree.

> 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.
