Creating a Kafka Role

This section describes how to create and configure a Kafka role.

Users can create Kafka roles only in security mode.

If the current component uses Ranger for permission control, you need to configure permission management policies based on Ranger. For details, see Adding a Ranger Access Permission Policy for Kafka.
