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
