> With KNOX-2714, end-users can create tokens on behalf of other users using
> Hadoop's impersonation mechanism.
> The problem with the current implementation is that the proxyuser
> authorization happens to be on service level, but it should be executed
> sooner.
> As discussed offline with [~lmccay] and [~pzampino] we agreed on the
> following:
> * impersonation support should be done in Knox's identity assertion layer
> and not in the services
> * the proxuyser authorization in HadoopAuth filter should be left as-is.
> When someone configures them in two places (HadoopAuth authentication and in
> identity-assertion), a WARN-level message should indicate that one on the
> identity-assertion level will be ignored.
