Hi Noah, sadly there's no generic guide on how to approach Flink logs. What exactly do you mean by "the job hangs"? Did you verify via the metrics that it is not making any progress anymore at all? If so, are all operators affected, or just some?
If your Flink cluster really is stuck, and you are certain that the sources are receiving data, then I'd suggest to to a ThreadDump of some TaskManagers to see where they are stuck.
