Hadoop2.7.1 配置三个.xml文件的创建地址

我最初是hadoop1.0.1,已经搭建好了的，现在想把它换成2.7.1，结果起来之后，只有JPS服务起来了，其他几个没有服务没有起来，我见网上说的是在写权限不够16/03/01 21:21:00 WARN namenode.NameNode: Encountered exception during format:
java.io.IOException: Cannot create directory /home/hadoop/leen/hadoop/tmp/dfs/name/current
这个文件的时候权限不够，但是我现在用的是root权限啊！求大神指点，相关的配置文件是按照这个链接博文写的，稍微结合自己的做了修改，希望大家能帮忙指点一下
