What does "reachableHost" mean here? I understand that it is not really the
"listeningHost" any more (that is the wildcard address), but I don't understand
what "reachableHost" should mean.
> 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 Coordination
> Reporter: Robert Metzger
> Assignee: Maximilian Michels
>
> 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.
