             Summary: Change Akka configuration to allow accessing actors from different URLs
                 Key: FLINK-2821
                 URL: https://issues.apache.org/jira/browse/FLINK-2821
             Project: Flink
          Issue Type: Bug
          Components: Distributed Runtime
            Reporter: Robert Metzger


Akka expects the actor's URL to be exactly matching.

As pointed out here, cases where users were complaining about this: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Error-trying-to-access-JM-through-proxy-td3018.html

  - Proxy routing (as described here, send to the proxy URL, receiver recognizes only original URL)
  - Using hostname / IP interchangeably does not work (we solved this by always putting IP addresses into URLs, never hostnames)
  - Binding to multiple interfaces (any local 0.0.0.0) does not work. Still no solution to that (but seems not too much of a restriction)


I am aware that this is not possible due to Akka, so it is actually not a Flink bug. But I think we should track the resolution of the issue here anyways because its affecting our user's satisfaction.
