Amazon EMR 的服務角色 (EMR 角色)
Amazon EMR 角色會在佈建資源和執行服務層級的任務 (這些任務不會在執行叢集內 Amazon EC2 執行個體的內容中執行) 時，定義 Amazon EMR 允許的動作。例如，服務角色用於在叢集啟動時佈建 EC2 執行個體。
-
預設角色名稱為
EMR_DefaultRole_V2。 -
附接至
EMR_DefaultRole_V2的 Amazon EMR 範圍預設受管政策是AmazonEMRServicePolicy_v2。此 v2 政策會取代已棄用的預設受管政策AmazonElasticMapReduceRole。
AmazonEMRServicePolicy_v2 取決於 Amazon EMR 佈建或使用的資源的範圍縮小存取權。使用此政策時，您需要在佈建叢集時傳遞使用者標籤 for-use-with-amazon-emr-managed-policies = true。Amazon EMR 將自動傳播這些標籤。此外，您可能還需要手動將使用者標籤新增至特定類型的資源，例如非 Amazon EMR 建立的 EC2 安全群組。請參閱 標記資源以使用受管政策。
重要
Amazon EMR 使用此 Amazon EMR 服務角色和 AWSServiceRoleForEMRCleanup 角色來清除帳戶中不再使用的叢集資源，例如 Amazon EC2 執行個體。必須包含角色政策的動作，才能刪除或終止資源。否則，Amazon EMR 無法執行這些清除動作，保留在叢集上的未使用資源可能會產生費用。
以下顯示目前 AmazonEMRServicePolicy_v2 政策的內容。您也可以在 IAM 主控台上查看 AmazonEMRServicePolicy_v2

您的服務角色應使用下列信任政策。
重要
下列信任政策包括 aws:SourceArn 和 aws:SourceAccount 全域條件金鑰，這些金鑰會將您授予 Amazon EMR 的許可限制在帳戶中的特定資源。使用它們可以保護您免受混淆代理人問題。
