SLAVE Broker 为什么会不停删除topic和consumer group

[zergduan]

我部署了2M-2S without Controller集群，每个Slave Broker的Broker.log都在不停地出现：

delete topic config OK, topic: XXX
delete subscription group OK, subscription group: XXX

这些日志都是INFO，看上去似乎每次SLAVE从Master获取到topic和consumer group的信息后，立即又删除了所有的topic和consumer group配置

这种SLAVE不停删除topic和consuner group的情况再4.9中不曾出现，这正常么？
