发现是clusterId 不匹配



解决办法1：

  1. 进入 config 
cd /export/servers/kafka_2.12-2.4.1/config
  1. cat server.properties 找到 log.dirs的配置项，小编的是 log.dirs=/export/servers/kafka_2.12-2.4.1/data
  2. 进入 data,修改 meta.properties 文件

把 cluster.id= 改成 Cluster ID的值，小编的是： F5_E0Y5hRaaG9s_xgm5qpg



解决方法2：

根据 log.dirs=/export/servers/kafka_2.12-2.4.1/data 这个配置项，进入data文件夹下

cd /export/servers/kafka_2.12-2.4.1/data

删除所有的文件和文件夹，并重新执行： nohup bin/kafka-server-start.sh config/server.properties &
