Sorry, I've made a mistake, the user group hadoop also do not have write permission :(

Updated ways to fix your problem:

  1.  Add write permission for other group
  2.  Add user dyf to user group hadoop, and add write permission for user group hadoop.

Or if you do not want to enable the authorization, just change the value of hadoop.security.authorization
to false.

The permission of  of / is 'hadoop:hadoop:drwxr-xr-x', your user name is dyf, you're not the
owner, I guess you're also not belong to the user group 'hadoop', so you do not have the write
permission.
Two ways to fix this:

  1.  Add dyf to user group hadoop
  2.  Change the permission of /, add write permission for other group
