             Summary: Change visibility of aclMatch in SimpleAclAuthorizer to protected to allow overriding in subclasses
                 Key: KAFKA-6561
                 URL: https://issues.apache.org/jira/browse/KAFKA-6561
             Project: Kafka
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.0.0
            Reporter: Sönke Liebau
            Assignee: Sönke Liebau


Currently the visibility of the [aclMatch|https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/security/auth/SimpleAclAuthorizer.scala#L146] function in the SimpleAclAuthorizer class is set to private, thus prohibiting subclasses from overriding this method. I think this was originally done as this function is not supposed to be part of the public Api of this class, which makes sense.
However when creating a custom authorizer this would be a very useful method to override, as it allows to reuse a large amount of boilerplate code around loading and applying ACLs and simply changing the way that ACLs are matched.

Could we change the visibility of this method to protected, thus still keeping it out of the public interface but allowing for subclasses to override it?
