Your SSH isn't setup properly

Setup passphraseless ssh

Now check that you can ssh to the localhost without a passphrase:

$ ssh localhost

If you cannot ssh to localhost without a passphrase, execute the following commands:

$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

Execution

Format a new distributed-filesystem:

$ bin/hadoop namenode -format

Start The hadoop daemons:

$ bin/start-all.sh
