------------------------------------------------------------

Best case I think we can verify that it fails more gracefully.  The current rewrite rules will still require the presence of a port.  That being said we should verify this for 0.5.0.  We should file a different jira if we want to support Knox behind xinetd.

> Has anyone had any success using a port forwarder (like xinetd) to forward 443 to knox gateway 8443?
> I keep getting this exception: 
> 2014-05-13 17:41:13,976 ERROR hadoop.gateway (GatewayServlet.java:service(122)) - Failed to execute filter: javax.servlet.ServletException: org.apache.shiro.subject.ExecutionException: java.security.PrivilegedActionException: javax.servlet.ServletException: java.lang.NullPointerException
> My initial thought is that the knox url rewriting mechanism is expecting the port '8443' to exist?
