获取EMR集群克隆元数据信息,便于通过 CreateCluster API快速创建集群。
调试
您可以在OpenAPI Explorer中直接运行该接口,免去您计算签名的困扰。运行成功后,OpenAPI Explorer可以自动生成SDK代码示例。
授权信息
下表是API对应的授权信息,可以在RAM权限策略语句的Action
元素中使用,用来给RAM用户或RAM角色授予调用此API的权限。具体说明如下:
- 操作:是指具体的权限点。
- 访问级别:是指每个操作的访问级别,取值为写入(Write)、读取(Read)或列出(List)。
- 资源类型:是指操作中支持授权的资源类型。具体说明如下:
- 对于必选的资源类型,用背景高亮的方式表示。
- 对于不支持资源级授权的操作,用
全部资源
表示。
- 条件关键字:是指云产品自身定义的条件关键字。
- 关联操作:是指成功执行操作所需要的其他权限。操作者必须同时具备关联操作的权限,操作才能成功。
