GUYS I'm using this tutorial 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
