Azure data factory 数据工厂服务主体的ACL验证失败，尽管它具有rwx权限

我有一个U-SQL脚本，它使用我的个人凭据从VS代码成功执行，但从数据工厂管道触发时失败。我的个人帐户拥有Azure订阅的所有者权限。ADF通过Data Lake Analytics&Store使用服务主体身份验证

我正在使用Data Factory V2和Data Lake Gen1以及默认的集成运行时。ADLA防火墙已禁用

U-SQL脚本非常简单，它只从CSV文件中读取数据，然后尝试将其写入另一个CSV文件中。以下是整个脚本：

@companies = 
    EXTRACT
        Id string,
        Name string
    FROM @InputFile
    USING Extractors.Csv(skipFirstNRows: 1);

OUTPUT @companies
    TO @OutputFile
    USING Outputters.Csv(outputHeader: true);

参数InputFile和OutputFile包含到输入和输出数据的ADL路径。这些参数是从数据工厂传递的。脚本的第一阶段（“提取”）成功执行，图中显示错误发生在“PodAggregate”阶段。如果尝试将输出写入托管表而不是CSV文件，则会发生类似错误

Data Factory中的高级错误消息为：

错误Id:VertexFailedFast，错误消息：Vertex因fail fast错误而失败

Data Lake Analytics提供了更详细的错误：

E_STORE_USER_错误：在读取或写入数据时报告了用户错误

组件：存储
