Configure Permissions

Amazon EMR supports IAM policies. IAM is a web service that enables AWS customers to manage users and their permissions. You can use IAM to create user-based policies and attach them to users. The policies grant or deny permissions and determine what actions a user can perform with Amazon EMR and other AWS resources. For example, you can allow a user to view EMR clusters in an AWS account but not create or delete them. In addition, you can tag EMR clusters and then use the tags to apply fine-grained permissions to users on individual clusters or a group of clusters that share the same tag.

IAM is available at no charge to all AWS account holders. You don't need to sign up for IAM. You can use IAM through the Amazon EMR console, the AWS CLI, and programmatically through the Amazon EMR API and the AWS SDKs.

IAM policies adhere to the principle of least privilege, which means that a user can't perform an action until permission is granted to do so. For more information, see the IAM User Guide.
