Thanks Jeff for the solution. I think this is the right one. However, I
could find another fix. I found that inside the new Job class, the *
deprecated* class JobConf is used. Actually, there is an instance of it in
its parent class JobContext. So, I added the following line in my code and
now it is running:
((JobConf) job.getConfiguration()).setJar("/path/to/my.jar");

Farhan
