Amazon EMR 的服务角色(EMR 角色)

EMR 角色定义在预置资源,以及执行在集群中运行的特定 EC2 实例的上下文中不执行的服务级任务时,允许 Amazon EMR 执行的操作。例如,服务角色用于在集群启动时配置 EC2 实例。

  • 默认角色名为 EMR_DefaultRole

  • 附加到 EMR_DefaultRole 的 Amazon EMR 范围的默认托管策略是 AmazonEMRServicePolicy_v2。此 v2 策略替换了默认托管策略 AmazonElasticMapReduceRole,该策略即将弃用。

AmazonEMRServicePolicy_v2 取决于对 EMR 预置或使用的资源的范围缩小访问权限。使用此策略时,您需要在预置集群时传递用户标签 for-use-with-amazon-emr-managed-policies = true。EMR 将自动传播这些标签。此外,您可能需要手动向特定类型的资源添加用户标签,例如不是由 EMR 创建的 EC2 安全组。请参阅标记资源以使用托管策略

下面显示的是当前 AmazonEMRServicePolicy_v2 策略的内容。您还可以在 IAM 控制台上查看 AmazonEMRServicePolicy_v2 托管策略的当前内容。
