Ranganath Samudrala updated KAFKA-19022:
----------------------------------------
Description:
While migrating Kafka from zookeeper to kraft, we see errors in logs like
INCONSISTENT_CLUSTER_ID in FETCH response
or
INCONSISTENT_CLUSTER_ID in VOTER response
But cluster IDs being compared is not displayed in logs so there is not enough
information to see where the issue is. Is the class data *clusterId* empty
(which could potentially be a bug?) or incoming *clusterId* empty or incorrect?

private boolean hasValidClusterId(String requestClusterId) {
// We don't enforce the cluster id if it is not provided.
