>
> Now YarnClient will automatically get a timeline DT when submitting an app in
> a secure mode. It will try to parse the yarn-site.xml/core-site.xml to get
> the RM daemon operating system user. However, the RM principal and
> auth_to_local may not be properly presented to the client, and the client
> cannot translate the principal to the daemon user properly. On the other
> hand, AbstractDelegationTokenIdentifier will do this translation when create
> the token. However, since the client has already translated the full
> principal into a short user name (which may not be correct), the server can
> no longer apply the translation any more, where RM principal and
> auth_to_local are always correct.
