What are you doing within your testCluster.jar? If you are simply submitting a job, you can use a Driver method and get rid of all these hassles. JobClient and Job classes both support submitting jobs from Java API itself. Please read the tutorial on submitting application code via code itself: http://developer.yahoo.com/hadoop/tutorial/module4.html#driver Notice the last line in the code presented there, which submits a job itself. Using runJob() also prints your progress/counters etc. The way you've implemented this looks unnecessary when your Jar itself can be made runnable with a Driver! -- Harsh J www.harshj.com
