    [ https://issues.apache.org/jira/browse/KNOX-1334?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16489758#comment-16489758 ] 

Larry McCay commented on KNOX-1334:
-----------------------------------

Hi [~ravipraveen] - I think this is a better topic for a discussion thread for a JIRA - at least at this point.

If you are looking to leverage the existing service definitions for those UIs for traffic coming to a Knox instance installed and exposed in EMR then that should work - at least to whatever degree those service definitions work today.

If you are looking to expose multiple ports on the Knox gateway to specific topologies for those UIs then you can look at Topology Port Mapping [1].

Hope that is helpful.

> Hi
> I have requirement to send all the request coming to proxy to be forwarded to EMR master node.
> Example:
> https://<any dns-name>:<PORT>/ --> Proxy --> EMR master.
> The DNS name could be anything, because there are many slave nodes. I would like the proxy to "redirect" dynamically "https://<any dns-name>:<PORT>/" to EMR master host. Could you please let me know if a reverse proxy/ Apache Knox can do that. I am trying to mimic option2 "SSH Tunnel to the Master Node Using Dynamic Port Forwarding"

> Sample URLS:
> YARN ResourceManager https://master-public-dns-name:8088/ YARN NodeManager https://slave-public-dns-name:8042/ Spark HistoryServer https://master-public-dns-name:18080/

> If so could you please share me the steps to configure Knox on EMR cluster- would be very helpful?
