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

Format a new distributed-filesystem:
# bin/hadoop namenode -format
Start the hadoop daemons:
# bin/start-all.sh

open port 50070 and 50030

Browse the web interface for the NameNode and the JobTracker; by default they are
available at:
NameNode - http://:50070/
JobTracker - http://:50030/
