Rol de servicio para Amazon EMR (rol de EMR)

El rol de Amazon EMR define las acciones permitidas para Amazon EMR al aprovisionar recursos y realizar tareas de nivel de servicio que no se llevan a cabo en el contexto de una instancia de Amazon EC2 que se ejecuta dentro de un clúster. Por ejemplo, el rol de servicio se utiliza para aprovisionar instancias EC2 cuando se lanza un clúster.

• El nombre del rol predeterminado es EMR_DefaultRole_V2.

• La política administrada predeterminada con ámbito de aplicación de Amazon EMR y asociada a EMR_DefaultRole_V2 es AmazonEMRServicePolicy_v2. Esta política, versión 2, sustituye a la política administrada predeterminada, AmazonElasticMapReduceRole, ya obsoleta.

AmazonEMRServicePolicy_v2 depende del acceso limitado a los recursos que Amazon EMR aprovisiona o utiliza. Cuando utilice esta política, tendrá que pasar la etiqueta de usuario for-use-with-amazon-emr-managed-policies = true al aprovisionar el clúster. Amazon EMR propagará automáticamente esas etiquetas. Además, es posible que tenga que agregar manualmente una etiqueta de usuario a tipos específicos de recursos, como grupos de seguridad de EC2 que no fueron creados por Amazon EMR. Consulte Etiquetado de recursos para usar políticas administradas.

importante

Amazon EMR utiliza este rol de servicio de Amazon EMR y el rol AWSServiceRoleForEMRCleanup para limpiar los recursos del clúster de su cuenta que ya no utiliza, como las instancias de Amazon EC2. Debe incluir acciones para que las políticas de rol eliminen o terminen los recursos. De lo contrario, Amazon EMR no podrá realizar estas acciones de limpieza y podría incurrir en costos por los recursos no utilizados que permanecen en el clúster.

A continuación se muestra el contenido de la política AmazonEMRServicePolicy_v2. También puede ver el contenido actual de la política AmazonEMRServicePolicy_v2administrada en la consola de IAM.

Su rol de servicio debe usar la siguiente política de confianza.

importante

La siguiente política de confianza incluye las claves de condición globales aws:SourceArn y aws:SourceAccount para limitar los permisos que concede a Amazon EMR a determinados recursos de su cuenta. Con estas, podrá protegerse contra el problema del suplente confuso.
