> 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 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.
