operating system you are using will be of good help to answer your question.

Normally the command you are looking for is provided by "openssh-clients"
Install this package if not already.

If installed normally on a redhat system its placed at /usr/bin/ssh-copy-id

Master:~ mediaadmin$ ssh pluto@Slave
Last login: Thu Oct 25 17:15:16 2012 from 10.203.33.80
plutos-iMac:~ pluto$

now if I run command start-dfs.sh from Master logged in terminal it asks for passwords

Master:~ mediaadmin$ ssh master
Password:
Last login: Thu Oct 25 17:16:44 2012 from master
Master:~ mediaadmin$ start-dfs.sh
starting namenode, logging to /HADOOP/hadoop-0.20.2/bin/../logs/hadoop-mediaadmin-namenode-Master.out
Password:Password: abc
Password: abc
Password:
Master: Permission denied (publickey,keyboard-interactive).

I think master machine authorized-key  is missed.

Please do following..

ssh-copy-id -i ~/.ssh/id_rsa.pub {IP of Master machine}..

Before starting cluster better to check whether ssh is enable or not by doing ssh {slave or master IP} from Master ( here it should not ask passwd).

The most common cause of this (once the .pub is properly copied to
authorized_keys) is permissions problems. Make sure your .ssh/
directory is mode 700 (rwx------) and your .ssh/authorized_keys file
is mode 600 (rw-------) and your home directory is not group-writable.

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
chmod go-w ~

If the remote machine is running RHEL or CentOS, you might also have a
SELinux labelling problem.
https://bugzilla.redhat.com/show_bug.cgi?id=499343 and
http://bugs.centos.org/view.php?id=4959

The workaround is to use the restorecon command, but it is easy to
misuse and I am not an expert so I am uncomfortable providing explicit
instructions. Check your /var/log/auth.log or similar on the remote
host to see if it has messages explaining why pubkey authentication
was not allowed.
