如果是刚加配置期间，轮询启动产生的（有些节点安全策略还没加），可以忽视。

不好意思 解决了 有个节点配错了 但现在出现另一个问题

[2021-04-29 14:26:16,372] ERROR [Controller id=2, targetBrokerId=1] Connection to node 1 failed authentication due to: Authentication failed: Invalid username or password (org.apache.kafka.clients.NetworkClient)
[2021-04-29 14:26:16,580] ERROR [Controller id=2, targetBrokerId=1] Connection to node 1 failed authentication due to: Authentication failed: Invalid username or password (org.apache.kafka.clients.NetworkClient)
