> if the UDP server has used port 23456, the TCP can also use the same port at the same time. Ah that's a very good point. Maybe we should not bother with ports at all but rather focus on hostnames. The set of resolvable hostnames should change a lot less than ports; a bogus hostname (that we can check for beforehand whether it resolves to anything) could be a better approach. This hostname could be awfully specific like "flink-qs-client-test-unavailable-host" so the chances of conflicts are basically 0. -- This is an automated message from the Apache Git Service.
