Orchestrate and parameterize EMR Notebook Executions without graphical user interface access
EMR Notebooks is a service that provides a fully managed, Jupyter-based notebook to data scientists and engineers who write ad-hoc jobs and experiment with them. Now you can orchestrate EMR Notebooks in a non-interactive manner to run ETL workloads especially in production. Before this feature, executing notebooks required the Jupyter User Interface access through the AWS Management Console.
