I work with vanilla versions of components
- Apache Kafka 3.3.2 Scala 2.12
- Apache Ranger 2.3.0
server.properties: authorizer.class.name=org.apache.ranger.authorization.kafka.authorizer.RangerKafkaAuthorizer
The necessary libraries copied to $KAFKA_HOME/libs
- ranger-kafka-plugin-impl/
- ranger-kafka-plugin-shim-2.3.0.jar
- ranger-plugin-classloader-2.3.0.jar
When starting kafka, I get an error

It looks like a library version conflict, maybe Ranger is compiled wrong
Do you have any ideas how to fix it?
UP: Apparently there is a version conflict I compiled the Ranger version from the wizard and there is not this error... It is a pity that the problem is not solved in the stable version of ranger 2.3 or 2.4
