I'm trying to install Hadoop 2.2.0 on a Single Node Cluster on my computer using this tutorial <http://codesfusion.blogspot.gr/2013/10/setup-hadoop-2x-220-on-ubuntu.html?m=1> . 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 :

```
hduser@victor-OEM:/usr/local/hadoop/sbin$ start-dfs.sh
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
