The instructions say to run "hdfs namenode -format" but you ran "hdfs -format".
Either "hadoop namenode -format" or "hdfs namenode -format" should work fine.
The jugnu-life instructions are suboptimal on a few points; just from
a quick glance I notice
- the instructions install a 32-bit JVM, hadoop strongly prefers a 64-bit JVM.
- DSA ssh keys are deprecated, the default RSA keys work better.
- config files go in /etc/hadoop/conf/ but the instructions say /etc/hadoop/.
