Sorry, I've made a mistake, the user group hadoop also do not have wri= te 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 val= ue of hadoop.security.authorization to false.

The permission of  of / is 'hadoop:hadoop:drwxr-xr-x', you= r user name is dyf, you're not the owner, I guess you're also not belong to the use= r 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 wr= ite permission for other group
