> Apache Knox's gateway is nice in that it can provide centralized
> authentication and authorization for a collection of service. Additionally,
> it can expose "private" nodes through a single point (e.g. a gateway). This
> makes our life as developers much easier in cloud deployments where it's not
> straightforward to access nodes (e.g. they're running on some private
> network).
> KNOX-1866 captures the changes over there required to make HBase's proxying
> actually work (definition lives there), but there were a few things we do in
> our UI which made it hard/impossible to proxy it correctly.
> * ProfilerServlet was dropping extra query parameters in the URL
> * JSON task output on master/regionserver couldn't be disambiguated
> * Some missing /master-status and /rs-status links couldn't be disambiguated
> properly due to a lack of context
> * Missing content-type set on a profiler servlet response
