> Key: YARN-3614
> URL: https://issues.apache.org/jira/browse/YARN-3614
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.5.0
> Reporter: lachisis
> Priority: Critical
>
> FileSystemRMStateStore is only a accessorial plug-in of rmstore.
> When it failed to remove application, I think warning is enough, but now
> resourcemanager crashed.
> Recently, I configure
> "yarn.resourcemanager.state-store.max-completed-applications" to limit
> applications number in rmstore. when applications number exceed the limit,
> some old applications will be removed. If failed to remove, resourcemanager
> will crash.
> The following is log:
