Apache Flink

Hey y'all, I'm trying to work build / run tests on Flink locally and I'm having issues, I think with my company's security software, because the `pekko` tests try to connect to my machine's local-but-external ip (ie `10.0.0.whatever`.) Is there a property or something else I can just `-D` in order to force pekko to use localhost instead of whatever discovery mechanism it's doing?

Actually seems like a more general question, my bad. Pekko falls back to `getLocalHost`

I think I struggled with similar issue while trying to run integration tests on my company's machine: <https://github.com/apache/flink/pull/27820>

Yeah, same sort of issue. I was able to partially work around it by setting my system's hostname to `localhost`

(Internally it works by calling `gethostname()` and then resolving DNS on that)

But then I ran into some other weird networking errors, which may be because my hostname was set to `localhost`.
