无论您是使用用户代管的服务账号，还是使用集群中虚拟机上的默认 Compute Engine 服务账号，都必须向 Cloud Data Fusion 授予 Service Account User 角色。否则，Cloud Data Fusion 无法预配 Dataproc 集群，并且在执行数据流水线时会显示以下错误：
PROVISION task failed in REQUESTING_CREATE state for program run [pipeline-name] due to Dataproc operation failure: INVALID_ARGUMENT: User not authorized to act as service account '[service-account-name]'
获取服务账号名称
在 Google Cloud 控制台中，前往 Identity and Access Management 页面。 转到 IAM 页面。
从页面顶部的项目选择器中，选择 Cloud Data Fusion 实例所属的项目、文件夹或组织。
找到并复制 Cloud Data Fusion 服务账号名称。请使用以下格式：service-[project-number]@gcp-sa-datafusion.iam.gserviceaccount.com。

Otherwise,\nCloud Data Fusion cannot provision a Dataproc cluster\nand the following error appears when you execute a data pipeline:\n\n`PROVISION task failed in REQUESTING_CREATE state for program run [pipeline-name] due to Dataproc operation failure: INVALID_ARGUMENT: User not authorized to act as service account '[service-account-name]'`\n\nGet the service account name\n----------------------------\n\n1. In the Google Cloud console, go to the Identity and Access Management page. \n [Go to the IAM page](https://console.cloud.google.com/iam-admin/iam)\n2. From the project selector at the top of the page, choose the project, folder, or organization to which the Cloud Data Fusion instance belongs.\n3. Find and copy the [Cloud Data Fusion service account](/data-fusion/docs/concepts/service-accounts#service_account_table) name. Use the following format: `service-[project-number]@gcp-sa-datafusion.iam.gserviceaccount.com`.\n\nGive service account user permission\n------------------------------------\n\n1. In the Google Cloud console, go to the **Service Accounts** page. \n [Go to the Service Accounts page](https://console.cloud.google.com/iam-admin/serviceaccounts)\n2. Click **Select a project** , choose a project where the service account you want to use for the Dataproc cluster is located, and then click **Open**.\n3. Click the email address of the [Dataproc service account](/dataproc/docs/concepts/configuring-clusters/service-accounts).\n\n | When Cloud Data Fusion provisions a Dataproc cluster, you can specify which user-managed service account to use for the Dataproc virtual machines in that cluster. If a service account is not specified, the default Compute Engine service account is used, which is in the format of `[project-number]-compute@developer.gserviceaccount.com`.\n4. Click the **Permissions** tab. The page displays a list of principals that\n have been granted roles on the service account.\n\n5. Click person_add **Grant access**.\n\n6. In the **New principals** field, paste the Cloud Data Fusion service\n account name that you previously copied.\n\n7. Select the **Service Account User** role.\n\n8. Click **Save**.\n\nGrant roles to Dataproc service accounts\n----------------------------------------\n\n### Grant runner role permission\n\nGrant the [Cloud Data Fusion runner role](/iam/docs/understanding-roles#cloud-data-fusion-roles)\n(`roles/datafusion.runner`) to service accounts that are used by\nDataproc. This authorizes the Dataproc service\naccount to run Cloud Data Fusion pipelines in your [project](/data-fusion/docs/concepts/security#projects).\nFor more information, see [Requiring permission to attach service accounts to resources](/iam/docs/service-accounts-actas).\n\n### Grant Cloud Storage admin permission\n\nIn Cloud Data Fusion versions 6.2.0 and above, grant the\n[Cloud Storage admin role](/storage/docs/access-control/iam-roles#standard-roles)\n(`roles/storage.admin`) to service accounts that are used by\nDataproc in your [project](/data-fusion/docs/concepts/security#projects).\n\nWhat's next\n-----------\n\n- Learn more about [Access control](/data-fusion/docs/access-control) in Cloud Data Fusion.\n- Learn more about Cloud Data Fusion [service accounts](/data-fusion/docs/concepts/service-accounts)."]]
