GUYS I'm using this tutorial [How to install Hadoop?](https://askubuntu.com/questions/144433/how-to-install-hadoop)
I mean the one made by Luis Alvarado in one of the comments ..
So I'm on Ubuntu 13.10 64bit 
Hadoop version is 2.2.0 

Actually I'm a total newbie on Hadoop .. Its new for me and We guys are trying to work on some Big Data related project 
I count you guys.. Help me!
I know tutorial is based on earlier versions of Hadoop but I managed to make it through the 11th step!
And the output of the step is 

```

root@sandesh-Inspiron-1564:/home/hduser/hadoop# sudo ./bin/hadoop namenode -format
