kafka报错（一）：Configured broker.id 0 doesn't match stored broker.id 1 in meta.properties

我们在配置kafka时可能会修改brokerid，这个时候启动可能会遇到报错
报错详细信息：

[2018-09-03 07:51:10,759] ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
kafka.common.InconsistentBrokerIdException: Configured broker.id 0 doesn't match stored broker.id 1 in meta.properties. If you moved your data, make sure your configured broker.id matches. If you intend to create a new broker, you should remove all data in your data directories (log.dirs).

从报错中可以看出是配置文件server.properties中的id与 meta.properties中的id不一致导致的。修改两个配置文件id一致就好了。meta.properties的路径在log.dirs下。
