Roshan Punnoose updated KNOX-365:
---------------------------------
Attachment: logs.zip
I have attached the logs from after reproducing the error on Knox 0.4.0. From
an initial look, it does look like the url cannot be rewritten and an NPE is
being thrown (Not sure?):

> 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?
