Hello, I recently integrated my Kafka broker with SSL authentication. I now am able to use SSL to authenticate the producer and consumer to the broker, and they can communicate as intended. Additionally, I implemented an access control list to limit access to the topics on the broker. However, when I try to consume all the messages from a specific topic using the --from-beginning flag, I only get the messages that have not yet been consumed.
I did some researching and found this post: https://jeqo.github.io/post/2017-01-31-kafka-rewind-consumers-offset/ This man was able to circumvent the issue by using the --offset flag, but our version of Kafka says that --offset is not a recognized option. I have been playing around with this issue for a while and have been unable to find a way around this problem. I need to be able to view all messages from a topic, regardless of if they have been consumed or not. I noticed that I cannot remove the consumer from a group because authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer then denies the consumer's requests. Is there a way to view all messages, while still using consumer groups, an access control list, and SSL authentication?
