Amazon EMR now supports Amazon S3 Access Points, a feature of Amazon S3 that allows you to easily manage access for shared data lakes. Using your S3 Access Point alias, you can simplify your data access at scale on Amazon EMR.
As you build more data lakes on S3, managing access for hundreds of users and applications on a shared datasetcan become complex. With S3 Access Points, you can simplify your access control for different applicationsrunning on your Amazon EMR cluster.
For example, you can create a single shared data lake for your organization on S3. You can create hundreds of S3 Access Points on the shared data lake, each corresponding to a department in your organization and with specific access permissions. You can then use each department’s corresponding S3 Access Point with your Amazon EMR application, and provide access only to the specific data needed.
