----------------------------------
Summary: WebUI changes to enable Apache Knox UI proxying
Key: HBASE-22467
URL: https://issues.apache.org/jira/browse/HBASE-22467
Project: HBase
Issue Type: Improvement
Components: UI
Reporter: Josh Elser
Assignee: Josh Elser
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
