cadonna opened a new pull request, #14980: URL: https://github.com/apache/kafka/pull/14980
If multiple addresses are available. This change is a follow-up to #9902. When re-resolving DNS after disconnecting, it is possible (likely, even) that we will resolve the same set of addresses in the same order, meaning we could attempt to reconnect to the same IP that we just disconnected from. In the case where we disconnected from the IP address because it has become unhealthy (due to a load balancer going down or a network routing layer restarting, for example), the client will need to time out before connecting to the next IP. This essentially unifies the behavior before and after KAFKA-12193: re-resolve after disconnecting while still progressing through the IP list.
