[2019-07-28 12:58:44,824] FATAL Shutdown broker because all log dirs in /develop/kafka_2.11-1.0.0/logs have failed (kafka.log.LogManager)

原因：kill -9 强制杀掉kafka进程，导致停止kafka时某些步骤没有处理，比如replication-offset-checkpoint文件没有处理好。

解决方法：备份/develop/kafka_2.11-1.0.0/logs/replication-offset-checkpoint文件，删掉该文件，然后重启kafka，就好了。
