> When a Dataset API is used that either requires or is modeled as a UDF, the class defining the UDF/function should be uploaded to the service fist using the `addArtifact()` API.
> When this is not done, an error is thrown. However, this error message is cryptic and is not clear about the problem.
> Improve this error message to make it clear that an expected class was not found.
