I would recommend that you first go through this
video<http://www.youtube.com/watch?v=ziqx2hJY8Hg>and this
blog<http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/>.
These would clear out your concept as well as your current problem and
provide the base for your further progress,
