-----------------------------------
Summary: Avoid authorization check in the group coordinator
Key: KAFKA-18857
URL: https://issues.apache.org/jira/browse/KAFKA-18857
Project: Kafka
Issue Type: Improvement
Reporter: Dongnuo Lyu
In kafka-18813, we pass the authorizer to the group coordinator in order to
check the topic describe authorization for the subscribed topics resolved from
regex.
Ideally we want to do the authz check only in KafkaApis, so we should consider
split the `consumerGroupHeartbeat` to first return a list of topics to check or
other ways to avoid the authorization check in the coordinator.
