Review Comment:
Instead of creating a dummy field to touch the parameter, consider using a
@nowarn annotation on the class or the mapOutputTracker parameter itself. This
would be clearer and more idiomatic. For example, you could annotate the
mapOutputTracker parameter with @nowarn("cat=unused") in the parameter list.
