Description

ENV:
knox 1.3
Knox , HDFS , Hbase , Impala is installed in HA

Steps :
1. Create a topology_1 with HDFSUI,HBASEUI,IMPALAUI services
2. Login to knox homepage
3. Expand topology_1
4. Access any one of the link for HDFS / Hbase/Impala instance via knox proxy

Observation;
the knox gateway url link for HDFS / Hbase/Impala will expose the underlying service address as part of the query param for example as follows.

https://<knox_host>:8443/gateway/topology_1/hbase/webui/master?&host=<hbase_host1>&port=22002

Suggestion :
Since exposing the service address in knox gateway url is against proxying concept , we should have a mechanism to avoid exposing the service address to the end user.
