chernyih opened a new pull request, #12131: URL: https://github.com/apache/kafka/pull/12131
When a client connects to a SSL listener using PLAINTEXT security protocol, after the TCP connection is setup, the client considers the channel setup is complete. In reality the channel setup is not complete yet. The client then resets reconnect exponential backoff and issues API version request. Since the broker expects SSL handshake, the API version request will cause the connection to disconnect. Reconnect will happen without exponential backoff since it has been reset. The proposed fix is not to reset reconnect exponential backoff when sending API version request. In the good case where the channel setup is complete, reconnect exponential backoff will be reset when the node becomes ready, which is after getting the API version response. The fix doesn't cover the case where clients do not send API version request and go directly to ready state. -- This is an automated message from the Apache Git Service.
