Hi, Can you pls let me know if this is resolved or any work around is there. I am using Kafka 0.11.0.1 version.
a. When incorrect credentials are sent the publisher or consumer API, logs below warning error , but keeps retrying to broker with out disconnecting. b. We are using kafka as middleware application for multiple pubs and subs. So if any one use wrong password , the broker will also be busy and see as performance issue, right?

This may indicate that authentication failed due to invalid credentials.
