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

[~ravipraveen] - you should be directing such questions to the user@ and/or 
dev@ lists rather than on a Jira with a patch for specific unrelated issues.

It seems that the Jira title of the Jira is a bit vague, so I will change it to 
reflect what the description and the attached patch seem to address.

I do not want to lose the discussion that was happening prior to your question 
either.

So let's keep additional topics on the email list or other JIRAs if you plan to 
provide a patch.

> 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"
> https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-ssh-tunnel.html
> 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/
> [https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-ssh-tunnel.html]
>  
> If so could you please share me the steps to configure Knox on EMR cluster- 
> would be very helpful?
> Praveen.
