It works fine on the single node setup but on multiple node simple word-count python example didn't work...  I read on the blog that it might be the problem in the version I am using. So I thought to change the version and downloaded the Hadoop 2.2.0. This version has yarn together with many new features that I hope I will learn in the future. Now simple wordcount example works without any problem on the multi-node setup. I am using simple python example.
