Description

What you would like to be added?

The goal of the issue is to expose a main_class parameter on the FileJob dataclass to enable jar file submission.

Why is this needed?

The Spark SDK KEP proposes a main_class parameter on the FileJob dataclass.

However, the current implementation for FileJob does not support this parameter. As such, jar file submission is not enabled on the Spark SDK.
