First check whether hadoop processes (namenode, secondarynamenode, 
jobtracker and tasktracker) are running in your clusters or not. Use "ps 
-ef" for it. If they are running then you can try any example inside 
hadoop tarball or just try to copy data from your local filesystem to 
hdfs and back. If the processes are not running than u need to check the 
hadoop conf files and your java environment. There are lot of good 
tutorials on internet to start with configuration.
