no output or error i.e there's no action happened have example.jar firstjoin class , hdfs input directory , copied file also. suggesion in advance

1.first check jar runnable jar or normal jar
2.if normal jar may have provide package name if package exists
3.if runnable jar make sure while creating runnable jar point driverclass/main class. 4.if above 2 not issue check typing hadoop dfs -ls / , check if directory shows or not.
5.try formating namenode , restarting cluster again...
let me know if anyof works..
