EMR Notebooks AWS

Notebooks can be launched directly from the Amazon EMR console by users with appropriate IAM permissions

EMR Notebooks (now EMR Studio Workspaces) provide a managed Jupyter Notebook/JupyterLab environment for interacting with Amazon EMR clusters

EMR Notebooks have several statuses: Starting, Ready, Pending, Stopping, Stopped, and Deleting, each affecting what actions can be performed

Only one user can open a specific EMR notebook at a time; attempting to open an in-use notebook results in an error

Deleting a notebook from the console does not remove the underlying .ipynb file from S3; manual deletion from S3 is required to avoid storage charges

Notebook files are stored in Amazon S3 and can be uploaded, downloaded, or replaced using the AWS CLI or S3 interface

Proper IAM policies and service roles are essential for secure access and S3 integration with EMR Notebooks
