Windows平台整合SpringBoot+KAFKA__第2部分_代码编写前传
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??

删掉日志文件夹中的文件
D:\kafka_2.12-2.4.0\kafka-logs
D:\kafka_2.12-2.4.0\logs
重启KAFKA,还是不行,报错日志一样
头皮有些麻了,我CA,删除完日志,算新部署好啊,不应该啊。
一通操作猛如虎,此处省略一万字,半个小时过去,终于

好吧,试试吧。
删除KAFKA的日志文件,再去zookeeper配置的DATA文件夹,删掉里面的文件;
重启
一切正常;
总结:
忘记了,KAFKA一定是要基于zookeeper的,如果KAFKA有异常,zookeeper要有连带责任的(开个玩笑)
因为是分布式,所以 zookeeper 那边有记录,哪怕kafka这端整个日志都被删除,zookeeper那边都有校验提示的,所以要做,一起都做,否则不过;
