org.apache.hadoop.security.AccessControlException: Permission denied: user=?, access=WRITE, inode="/":hadoop:supergroup:drwxr-xr-x 异常解决

进行如下更改：

vim /usr/local/hadoop/etc/hadoop/hdfs-site.xml

【我的hadoop目录在/usr/local下,具体的是修改你的hadoop目录中的/etc/hadoop/hdfs-site.xml】
添加一个property：
<property>
      <name>dfs.permissions</name>
      <value>false</value>
</property>

然后重新启动hadoop集群，走起，成功！
