If you have installed the hadoop software on the same locations on all
machines and if you have a common user on all the machines, then there
should be no explicit need to specify anything more on the slaves.
Can you tell us whether the above two conditions are true ? If yes, some
more details on what is failing when you run start-dfs.sh will help.
