TAO XIAO commented on KAFKA-3950:
---------------------------------
How about we still keep the filtering on client side and fix the broken piece?
Here is the trouble maker
[ConsumerCoordinator.java|https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/consumer/internals/ConsumerCoordinator.java#L150]
that fails the validation. Can we remove below check?
{code}
if (!cluster.unauthorizedTopics().isEmpty())
throw new TopicAuthorizationException(new
HashSet<>(cluster.unauthorizedTopics()));
{code}
As the authorization check has been done on server-side already when fetching
metadata all topics stored in {code}cluster.topics(){code} should the ones the
consumer has permission to read. We can simply return them that matches the
pattern to end user
