Joseph Witt updated NIFI-3561:
------------------------------
Fix Version/s: 1.2.0
> JettyWebSocketServer uses original requested port, instead of the forwarded
> port
> --------------------------------------------------------------------------------
>
> Key: NIFI-3561
> URL: https://issues.apache.org/jira/browse/NIFI-3561
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.1.0
> Reporter: Edgar Orendain
> Assignee: Koji Kawamura
> Labels: jetty, websocket
> Fix For: 1.2.0
>
>
> Situation:
> We have port forwarding set up in such a way where port 25000 is forwarded to
> port 15000. ListenWebSocket processor listens on this 15000 port.
> Requests that hit the JettyWebSocketServer are considered as attempting to
> connect to the original port (25000) rather than the forwarded port of 15000.
> The same was reproduced with different ports and on different forwarding
> layers (i.e. NAT and iptables). I've included a stack trace below.
> From Koji:
> -I think it's more of a Jetty side issue, after it upgrade HTTP connection to
> TCP, it still uses the original requested port (which is a port forwarding
> request to the real port) to find a request handler assigned to that port.-
> (updated) Excuse me, but I was wrong about this diagnose. It's a problem in
> NiFi JettyWebSocketServer I wrote. The ControllerService lookups server
> instance by a port number that the CS listens to. When a request made through
> port forwarding, a port passed by ServletUpgradeRequest is different than CS
> is bounded to. Then it fails to lookup a server instance. I will check if
> original port can be retrieved from a request, if not, I will add a
> configuration property to the CS to specify forwarding port numbers.
> java.lang.RuntimeException: No controller service is bound with port: 25000
