> Key: YARN-6967
> URL: https://issues.apache.org/jira/browse/YARN-6967
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.8.1

> YARN-6125 implemented {{BoundedAppender}} and applied to the field {{diagnostics}} to limit the diagnostic message's size.
> However, some code bypasses this limit. In {{RMAppAttemptImpl.rememberTargetTransitionsAndStoreState(...)}}, a local variable {{diags}} will finally be written into ZooKeeper if ZKRMStateStore is used.
> A simple fix is to also use {{BoundedAppender}} for the local variable.
