> Currently, DelegationTokenAuthenticationHandler only support DT operations 
> for the request user after it passes the authentication. However, it should 
> also support the request user to do DT operations on behalf of the proxy user.
> Timeline server is using the authentication filter for DT operations instead 
> of traditional RPC-based ones. It needs this feature to enable the proxy user 
> to use the timeline service (YARN-2676).
