password problem

HI..
I hav created my cluster with two nodes and the ssh is working perfectly.ut
when i try to start my hadoop, it is asking for slave's password though i
hav given the password option in config file to be empty. The data nodes are
not getting started. How do i proceed?

You have to use password less ssh. Generate a public keys and put them in
the authorized_keys files .ssh directory of other machines.Go through the
link.
