Depends on your configuration (security in core-site.xml;
hadoop.security.authorization). HDFS uses pam-auth, which means the user has
to exist. Maybe "su - USERNAME". Or you put the data into hdfs and change
the rights as the supergroup-member: hadoop dfs -chown -R USERNAME
/path/in/hdfs

Did you mean something like that?

 Alex
