-Re: Execute a Map/Reduce Job Jar from Another Java Program.

What happens? Is there an exception, does nothing happen? I am curious. Also how did you launch your other job that is trying to run this one. The hadoop script sets up a lot of environment variables classpath etc to make hadoop work properly, and some of that may not be set up correctly to make RunJar work.

Could you elaborate on how you used RunJar? What arguments did you
provide, and is the target jar a runnable one or a regular jar? What
error did you get?
