             Summary: Ensure clear error message when "new" consumer used with 
incompatible cluster
                 Key: KAFKA-17536
                 URL: https://issues.apache.org/jira/browse/KAFKA-17536
             Project: Kafka
          Issue Type: Improvement
          Components: clients, consumer
    Affects Versions: 3.9.0
            Reporter: Kirk True
            Assignee: Kirk True
             Fix For: 4.0.0


In Kafka 4.0, by default the consumer uses the updated consumer group protocol 
defined in KIP-848. When the consumer is used with a cluster that does not 
support (or is not configured to use) the new protocol, the consumer will get 
an unfriendly error about unavailable APIs. Since this error could be the 
user's first impression when attempting to upgrade to 4.0, we need to make sure 
that the error is very clear about the remediation steps (set the 
group.protocol to CLASSIC on the client or upgrade and enable the new protocol 
on the cluster).
