Richard Wise created KAFKA-9272: ----------------------------------- Summary: Error when trying to connect to SSL port using PLAINTEXT is very confusing Key: KAFKA-9272 URL: https://issues.apache.org/jira/browse/KAFKA-9272 Project: Kafka Issue Type: Bug Components: clients Affects Versions: 2.2.1 Reporter: Richard Wise
I accidentally forgot to set `security.protocol` to SSL when connecting to an SSL port, so connected via PLAINTEXT. I expected the Kafka client to fail immediately with a message about mismatched security protocols, but instead it failed saying that the topic does not exist and auto-creation was not enabled. This error message is very misleading and leads developers to think that the problem is the server configuration, not the client network security settings. -- This message was sent by Atlassian Jira (v8.3.4#803005)
