Run a simple spark-scala jar (hello-world) on existing running cluster

[19582]

I have created a simple hello-world jar that I would like to run as a job.

I also have an existing cluster. Now when I create a job to run on existing cluster, it fails for some unknown reason (don't see much in the errors), while if I run the same job on a new cluster, it runs fine. Any clue?

Thanks in advance.

Can you share screenshot and your example jar?
