Larry McCay commented on KNOX-1025:
-----------------------------------
Moving this out to 1.2.0 since there has been little movement on it and it
still requires test coverage. If you would like to get it in and have cycles to
close down on it in a week or so then please feel free to pull it back in.

> h2. Motivation
> In a multi-tenant doployment, end user need to access hadoop service in:
> {code:java}
> https://{gateway-host}:8443/gateway/eerie/webhdfs
> {code}
> , even with [KIP-6 Topology Port
> Mapping|https://cwiki.apache.org/confluence/display/KNOX/KIP-6+Topology+Port+Mapping],
> end user need to access in:
> {code:java}
> https://{gateway-host}:5443/webhdfs
> {code}
> we can give more convenience for end user, let them access in:
> {code:java}
> https://{eerie-specific-domain}/webhdfs
> or
> https://eerie.{gateway-domain}/webhdfs
> {code}
> There are some deploy prerequisites:
> # Let tenant admin add CNAME topology-specific-domain in their DNS server,
> point gateway host;
> # add CNAME eerie.gateway-domain in gateway domain DNS server, point geteway
> host;
> # add firewall rule in gateway host and redirect 443 to knox listening port
> 8443.
> h2. Configuration
> Configuration for this feature will be in gateway-site.xml config file.
