title: Hadoop : NameNode , DataNode and SecondaryNameNode are not running
body: <p>I'm trying to install Hadoop 2.2.0 on a Single Node Cluster on my computer using this tutorial <a href="http://codesfusion.blogspot.gr/2013/10/setup-hadoop-2x-220-on-ubuntu.html?m=1" rel="nofollow">http://codesfusion.blogspot.gr/2013/10/setup-hadoop-2x-220-on-ubuntu.html?m=1</a> . I follow every instruction I see, step-by-step but I have the same problem every time. NameNode , DataNode and SecondaryNameNode not running. The message I see when I enter start-dfs.sh , start-yarn.sh and jps is :</p>
