为什么数据网不能连接到卡夫卡?

原标题：Why can t Datanode connect to kafka?

I am running Milvus 2.3.11 and using bitnami kafka for my log broker. Due to many critical vulnerabilities in bitnami/kafka:3.1.0-debian-10-r52, I upgraded kafka to 3.7.0-debian-12-r6 After the upgrade datanode started throwing the following errors FAIL|rdkafka#consumer-6| [thrd:GroupCoordinator]: GroupCoordinator: milvus-kafka-0.milvus-kafka-headless.milvus-database.svc.cluster.local:9092: Failed to │ │ resolve milvus-kafka-0.milvus-kafka-headless.milvus-database.svc.cluster.local:9092 : Name or service not known (after 2ms in state CONNECT, 1 identical error(s) suppressed) I believe it is not able to connect to kafka. I ran nslookup milvus-kafka-0.milvus-kafka-headless.milvus-database.svc.cluster.local on a pod in the same namespace and it was able to resolve the host. But I have not idea why my datanode cannot connect to kafka. I reverted back to the previous deployment but I keep getting the same error. I have tried restarting both kafka and datanode pods but I get the same errors. Now, I am not sure if the error started before my kafka upgrade but I noticed it after the upgrade. Thanks in advance for your help.

I believe it is most likely a deployment issue, specifically might be with the network configurations on the Kafka side. Make sure your error level is set correctly so the all the info logs will display accordingly.
