>edit: Re-reading the PR description, I actually got it to work by setting
jobmanager.rpc.address to the external IP and getting rid of the hostname.
Glad you were able to solve the problem! :) Akka requires that all messages
are tagged with the same address which was used during initialization of the
receiver actor system. While this PR gets rid of the issue that an address
might not be available for binding during initialization of the receiver, it
still requires you to use a consistent address.
