我笔记本是win10

把localhost6给注释掉

然后重启虚拟机和hadoop试试？

为何 EMP-PC/192.168.1.1连接的是windows？？！！！！！


EMP-PC/192.168.1.1是什么

EMP-PC/192.168.1.1 to TestDemo-1:9001

为何 EMP-PC/192.168.1.1连接的是windows？？！！！！！

我windows远程连接我虚拟机的hadoop   
EMP-PC是我电脑名字 192.168.1.1是虚拟机的网关

EMP-PC/192.168.1.1

这个有问题 ，网关不行的，应该是你的ip地址。

各位大侠求助啦，我用是的hadoop2.6 搭的集群

集群规划：

这里面看不出什么来，去看看日志。
看看权限是否属于当前运行账号

版主，你好！我遇到了类似问题，报错如下，莫名出现master/192.168.101.128
（我的namenode结点），其他datanode并没挂掉，是HDFS或者yarn配置文件没配好吗？
