> 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.
> {code:java}
