Work Description: risdenk commented on issue #94: KNOX-1866 Fix HBase UI
proxying.
URL: https://github.com/apache/knox/pull/94#issuecomment-495681148
Hmmmm so there are 2 concerning errors in the logs when I tested this:
When visiting https://KNOX_HOST:8443/gateway/cluster_1/hbase/webui/
```
2019-05-24 08:34:43,981 ERROR knox.gateway
(UrlRewriteContextImpl.java:resolve(118)) - Failed to find values by parameter
name query.param.host: java.lang.NullPointerException
```
And when clicking on any of the links, end up with this:
https://KNOX_HOST:8443/gateway/cluster_1/hbase/webui/master/processMaster.jsp?host&port
```

> Time Spent: 20m
> Remaining Estimate: 0h
>
> There are lots and lots of edges in the HBASEUI service which render the
> system broken.
> I've been able to get everythign working exception the LogLevel servlet. The
> way this one is written in HBase fundamentally makes it impossible to proxy
> it as-is with Knox (at least, given my knowledge).
> There are some trivial HBase changes that need to go in first to make sure
> these rules work as expected.
