     [ https://issues.apache.org/jira/browse/KNOX-365?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kevin Minder resolved KNOX-365.
-------------------------------
    Resolution: Duplicate

Discovered and fixed the root cause in KNOX-439 where default ports 80 and 443 were being dropped for request URL in one of the servlet spec APIs.

> 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?
