Hi @Xiong Duan

• Kafka can’t assert the identity of client user over a non-secure channel. Thus, Kafka treats all users for such access as an anonymous user (a special user literally named ANONYMOUS).
• Ranger's public user group is a means to model all users which, of course, includes this anonymous user (ANONYMOUS).
