Using service-linked roles for Amazon EMR
Amazon EMR uses AWS Identity and Access Management (IAM) service-linked roles. A service-linked role is a unique type of IAM role that is linked directly to Amazon EMR. Service-linked roles are predefined by Amazon EMR and include all the permissions that the service requires to call other AWS services on your behalf.

For information about other services that support service-linked roles, see AWS services that work with IAM and look for the services that have Yes in the Service-linked roles column. Choose a Yes with a link to view the service-linked role documentation for that service.
