Hey, Had incident where one broker died and got later different IP address. Some clients / pods (everything lives on K8s) detected IP change and logged:
[Producer clientId=producer-1] Hostname for node 10000 changed from XXXX to > YYYY. (logged by org.apache.kafka.clients.ClusterConnectionStates) but many didn't and they couldn't actually send anything, continuously timing out. Any clue if there were some know issues with that and maybe something has been fixed in > 2.4.1? In the meantime I'm also checking DNS caching but nothing at OS-level but still verifying JVM (I'm using Java 14). -- BR, Michał Łowicki
