开始准备写测试代码

看半天不太懂（我也算是小白级别的，看我搞windows版本的kafka就知道了），

看文档无聊，偶然看到一个KAFKA的windows管理程序，于是就试试就装了一个，感觉那个玩意也比较垃圾，打算不用，突然看到上面可以管理 topic
于是我就当测试了，用这个管理工具删除我自定义的 test topic 后面操作比较快，我也懒得看结果，反正都是垃圾

中间接了个电话，回来，打算从零开始再弄一个JAVA测试类，心想这些个test topic 也没啥价值，干脆我重启 zookeeper/KAFKA得了；
于是关掉那两个CMD窗口，再启动这两个服务；
zookeeper启动正常；
KAFKA启动不正常，我心想，不是吧，啥玩意啊，这么容易坏？？
