> 创建topic时如果同时选择集群名和brokerName，默认会在该集群名下的所有broker中创建topic。如果只想在某个broker中创建topic，只需选择具体的broker，上面的集群名不要选。 “新增/更新”主体的时候，broker_name列表会把从节点也展示，是不是这个原因导致了就算只采用clusterName的方式去创建主体也会报错：Caused by: org.apache.rocketmq.client.exception.MQClientException: CODE: 1 DESC: Can't modify topic or subscription group from slave broker, please execute it from master broker.   -- This is an automated message from the Apache Git Service.
