1.First check the jar is runnable jar or normal jar
2.If this is a normal jar then you may have to provide package name as well if package exists
3.If it is a runnable jar make sure that while creating runnable jar you point to driverclass/main class. 4.If above two is not the issue check by typing hadoop dfs -ls / and check if the directory shows or not.
5.Try formating the namenode and restarting the cluster again...
Let me know if anyof this works..
