Andras Katona commented on RANGER-3231:
---------------------------------------
Yup, super helpful, thanks! It seems authorization request comes in with empty
actions, coming from cruise control metrics reporter. I'll modify my patch to
ignore these and answer an empty response, and also will check why this kind of
authorization calls happen.
> Ranger should use kafka Authorizer from KIP-504

> As described in the KIP, `org.apache.kafka.server.authorizer.Authorizer` is
> an improvement over `kafka.security.auth.Authorizer` and it's a pure Java
> interface (instead of Scala).
> `kafka.security.auth.Authorizer` has been deprecated since December 2019 and
> it will be removed in Apache Kafka 3.0 (roughly planned for July/August).
> See the KIP for more details:
