Describe the problem

Describe the problem or feature request clearly here.
I created a sparkmagic notebook in SageMaker. And connected it with my EMR following this guide.
https://aws.amazon.com/blogs/machine-learning/build-amazon-sagemaker-notebooks-backed-by-spark-in-amazon-emr/
And then I installed all the jars for my spark in EMR. And I want to import related packages in my notebook, but it did not work. How can I import them to my notebook? Any configuration need?
