解决eclipse中无法执行向hadoop上传文件问题

main…的问题

Permission denied: user=zhuy, access=WRITE, inode="/user":root:supergroup:drwxr-xr-x
从这句话我们可知道是权限问题

所以要修改权限在  hdfs-site.xml加入如下代码 （每台都要修改）

   <property>

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.
