Dataproc Metastore IAM 角色

Dataproc Metastore 定义了多个 Identity and Access Management (IAM) 角色。每个预定义角色都包含一组允许主账号执行特定操作的 IAM 权限。您可以使用 IAM 政策为主账号指定一个或多个 IAM 角色。

Identity and Access Management (IAM) 还提供创建自定义 IAM 角色的功能。您可以创建自定义 IAM 角色，并为该角色分配一项或多项权限。然后，您可以将新创建的角色授予主账号。使用自定义角色可创建访问权限控制模型，该模型将直接映射到您的需求以及可用的预定义角色。

本页面重点介绍与 Dataproc Metastore 相关的 IAM 角色。

准备工作

• 阅读 IAM 文档。

Dataproc Metastore 角色

IAM Dataproc Metastore 角色是一项或多项权限。您为主账号授予角色，以允许他们对项目中的 Dataproc Metastore 资源执行操作。例如，Dataproc Metastore User 角色包含 metastore.*.get 和 metastore.*.list 权限，这些权限允许用户获取和列出 Dataproc Metastore 服务、元数据导入、备份和项目中的操作。

下表列出了所有 Dataproc Metastore 角色以及与每个角色关联的权限：

注意 ：数据库和表权限用于启用了 gRPC 的 Dataproc Metastore 服务。它们在与使用 Thrift 端点的服务一起使用时没有任何影响。
