Philipp von dem Bussche commented on FLINK-2821:
------------------------------------------------

Hi [~mxm], I wanted to give this a try but I am not sure if I am testing this correctly.
Do I just have to set jobmanager.rpc.address but to the hostname that will be used for access from outside ?
I tried to use a name that is not resolvable on the host itself and that fails but this is on my local docker environment and this should be different as soon as I move this to rancher.
Thanks

> 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.
