【问题标题】：Azure stream anaytics with PowerBi Fails使用 PowerBi 的 Azure 流分析失败
【发布时间】：2017-07-13 16:45:46
【问题描述】：

我有一个流分析作业，它从 IoT 中心获取数据并将其发送到 PowerBi 和 azure 数据湖。单独编写数据 azure 数据湖可以完美运行，但是当我尝试将数据流式传输到 powerbi 时，我的蒸汽分析作业在首先写入输出后失败，并且我收到了以下错误日志。

任何工作失败的想法都是完美的。我很确定我在 power bi 应用程序的范围内。

【问题讨论】：

通常我们可以从活动日志中找到有用的信息，但是你得到的错误信息"JobFailedMessage": "The streaming job failed."非常笼统，很难找出问题所在。我想知道您是否在开始作业之前使用示例数据文件测试您的查询。

【解决方案1】：

您需要从流分析中授权 Power BI 订阅。
