Is there a reason why access cannot be given to the user on DFS during setup, using dfs -chmod or dfs -chown ? That seems a more correct solution. Please note that while some versions of Hadoop allowed user name to be set as a configuration property (I think it was called hadoop.job.ugi or some such), it will stop working with later, secure versions of Hadoop.
