这种问题：端口占用

解决方式

一首先确认自己的几个配置文件正确了如 slaves core 等等

防火墙，selinux需要关闭

二

用 sudo netstat -atunlp 查看下端口，如果占用直接 kill 就可以了

lz我出现了这个问题端口却并没有占用

查看了 datanode的日志，发现是ip地址没解析出来如下

根据ip地址解析没解析出来

所以需要在 core-site.xml配置文件中把主机名改为ip地址

保存下启动服务就可以

jps查看

还有注意下：

不能能用root权限登录来进行hadoop相关的操作

否则也会出错

如果用root权限登录了

好了你可以gg了卸载重新搭建了，

哎，昨天我也是这样的。搞得我连远程工具都慎用，
