>
> At present, HttpClientDispatch caches request entities while talking to
> services in secure cluster to replay the entity for a potential
> WWW-Authenticate challenge from service.
> This could be improved by leveraging delegation token coming down with the
> request to Knox. When we pass down the delegation token, we do not expect to
> see WWW-Authenticate challenge. When Knox gets request from client targeted
> to DataNode, it would always have DelegationToken. So, large files would be
> streamed straight without any buffering.
