一 问题描述

kafka启动失败，报错：

[2021-05-10 11:22:43,263] ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

kafka.common.InconsistentClusterIdException: The Cluster ID VLPFfY-WQkWmK7X9_C1aHQ doesn't match stored clusterId Some(0TVA9OzOTzCGMTqY50sBKA) in meta.properties. The broker is trying to join the wrong cluster. Configured zookeeper.connect may be wrong.

       at kafka.server.KafkaServer.startup(KafkaServer.scala:220)

       at kafka.server.KafkaServerStartable.startup(KafkaServerStartable.scala:44)

       at kafka.Kafka.main(Kafka.scala)

二 出错原因

我刚迁移zookeeper dataDir目录了。

三 解决办法

cd /tmp/kafka-logs  #kafka的Log.dirs路径

cp meta.properties meta.properties_bak

修改 meta.properties中的cluster.id值，示例：

我这里将0TVA9OzOTzCGMTqY50sBKA改成了VLPFfY-WQkWmK7X9_C1aHQ

四 总结

迁移zookeeper目录的话，也要修改meta.properties中的cluster.id值
