我正在尝试在Windows10上安装单节点hadoop。
我用过各种各样的指南，但都失败了。我最后用的是https://github.com/muhammadbilalyar/hadoop-on-window/wiki/step-by-step-hadoop-2.8.0-installation-on-window-10
我把我的dfs弄糊涂了

<property> 
    <name>dfs.replication</name> 
    <value>1</value> 
</property> 

<property> 
    <name>dfs.namenode.name.dir</name> 
    <value>file:///V:/DB/hadoop/namenode</value> 
</property>

<property> 
    <name>dfs.datanode.data.dir</name> 
    <value>file:///V:/DB/hadoop/datanode</value> 
</property>

格式化进行得很顺利。
不幸的是，当我跑的时候 start-all ，我进了一扇Windows

看起来它在本地windows路径规范方面有问题。怎么办？
