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。
| 操作 | 访问级别 | 资源类型 | 条件关键字 | 关联操作 |
|---|---|---|---|---|
| emr:GetClusterCloneMeta | get | *全部资源 * |
| 无 |
