我要评论kafka启动失败，查看日志文件发现如下错误：
error fatal error during kafkaserver startup. prepare to shutdown (
kafka.server.kafkaserver)
kafka.common.inconsistentclusteridexception: the cluster id scwt4v1zqpalgxvylowycw doesn't ma
tch stored clusterid some(abfhgigvr7g0jgojddv5oq) in meta.properties. the broker is trying to
join the wrong cluster. configured zookeeper.connect may be wrong.
解决：将kafka恢复到初始状态
1.删除kafka下的logs文件
2.将配置文件server.properties中配置的log.dirs=/opt/data/kafkadata中的数据清除
3.重新启动kafka即可，前提是启动zookeeper
