> In [https://github.com/apache/kafka/pull/15968/files], we changed the
> authorization logic slightly. If a produce request includes a topic name that
> doesn't exist and is not authorized, it now returns an
> UNKNOWN_TOPIC_OR_PARTITION error. Since topic name is sensitive information,
> it should return a TOPIC_AUTHORIZATION_FAILED error as before that PR.
> {code:java}
> else if (!metadataCache.contains(topicPartition))
> nonExistingTopicResponses += new TopicIdPartition(topicId,
> topicPartition) -> new PartitionResponse(Errors.UNKNOWN_TOPIC_OR_PARTITION)
> {code}
