> Currently MapRedLocalWork instance is a field at MapWork. This is MR specific
> where small table input to map join is always from a MapWork, which isn't
> true for other execution engine where works doesn't need to be chopped at RS.
> The refactoring moves the MapRedLocalWork to its parent class, BaseWork.
> Purely refactoring. No behavor change is expected. Test output might need to
> be updated though.
