Because of the way replication of topic partitions work internally, it is also important to grant topic access to brokers. Brokers replicating a partition will need to be authorized for both READ and DESCRIBE on that topic. DESCRIBE is granted by default with the READ authorization.
我在 https://docs.confluent.io 找到了这一段话,然后把新建topic的权限赋予所有brokers,这样就没问题了。
你不是用的acl么,listeners=PLAINTEXT://172.16.40.117:9092 这个就不对了呀
