1. 接口描述
接口请求域名: emr.tencentcloudapi.com 。
DescribeYarnApplications
默认接口请求频率限制:20次/秒。
推荐使用 API Explorer
点击调试
API Explorer 提供了在线调用、签名验证、SDK 代码生成和快速检索接口等能力。您可查看每次调用的请求内容和返回结果以及自动生成 SDK 调用示例。
2. 输入参数
以下请求参数列表仅列出了接口请求参数和部分公共参数,完整公共参数列表见 公共请求参数。
参数名称 | 必选 | 类型 | 描述 |
---|---|---|---|
Action | 是 | String | 公共参数,本接口取值:DescribeYarnApplications。 |
Version | 是 | String | 公共参数,本接口取值:2019-01-03。 |
Region | 是 | String | 公共参数,详见产品支持的 地域列表。 |
InstanceId | 是 | String | 集群ID 示例值:emr-xfyags1d |
StartTime | 是 | Integer | 起始时间秒 示例值:1686029737 |
EndTime | 是 | Integer | 结束时间秒,EndTime-StartTime不得超过1天秒数86400 示例值:1686129737 |
Offset | 是 | Integer | 分页偏移量,Offset=0表示第一页;如果limit=100,Offset=1,则表示第二页,数据第101条开始查询,返回100条数据;如果limit=100,Offset=2,则表示第三页,数据第201条开始查询,返回100条数据。依次类推 示例值:0 |
Limit | 是 | Integer | 分页大小,合法范围[1,100] 示例值:20 |
3. 输出参数
参数名称 | 类型 | 描述 |
---|---|---|
Total | Integer | 总数 |
Results | Array of YarnApplication | 结果列表 |
RequestId | String | 唯一请求 ID,由服务端生成,每次请求都会返回(若请求因其他原因未能抵达服务端,则该次请求不会获得 RequestId)。定位问题时需要提供该次请求的 RequestId。 |
