Kafka启动后很快自动关闭进程

今天kafka启动之后，刚开始输入jps还有进程，大概几秒钟不一会儿就关闭了，我这边是-daemon守护进程的方式启动的，到kafka下面的logs文件夹查看server.log日志发现了报错

我是一共有三台机器，输入jps发现每台机器的zookeeper都有进程在啊。在kafka配置摸索半天也没有结果，百度有人说kafka的server.properties和logs下面的meta.properties里面的broker Id要一样，我就把logs目录清空了，还是一样的问题。后来一想，难道是zookeeper的问题？

我就去看zookeeper的配置，果然发现了问题了。。原来是两台机器的myid配置成一样的数字的，把其中一台机器的myid换个数字（不能是0），结果成功了。
