hadoop,访问权限解决办法

?到服务器上修改hadoop的配置文件：conf/hdfs-site.xml, 找到增加配置(如果有的话则修改value的值为false)

覆盖默认的安全验证,修改完后需要重新启动hadoop服务


dfs.permissions
false

If "true", enable permission checking in HDFS.
If "false", permission checking is turned off,
but all other behavior is unchanged.
Switching from one parameter value to the other does not change the mode,
owner or group of files or directories.
