---------------------------------
We see similar issue in unsecure cluster too, like when trying to flex a
component with an invalid component name via CLI -
{code:java}
$ yarn app -flex sleeper-1 -component sleeper-bad 2

> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn-native-services
> Affects Versions: 3.1.0
> Reporter: Eric Yang
> Assignee: Eric Yang
> Priority: Major
> Attachments: YARN-7909.001.patch
>
>
> When kerberos is enabled, the response header will reply with:
> {code:java}
> Content-Type: application/json;charset=null{code}
> This appears to be somehow AuthenticationFilter is trigger charset to become
> undefined.
> The same problem is not observed when simple security is enabled.
