使用参考组件时出现U

本文介绍了使用参考组件时出现U-SQL错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用Azure API创建了一个U-SQL库，并在具有所有依赖项的Azure云上注册了程序集.我在U-SQL项目中添加了该库，并在U-SQL脚本中的

I created a U-SQL library using Azure APIs and register the assembly on Azure cloud with all dependencies. I added this library with my U-SQL project and added below line On my U-SQL script

USE master; REFERENCE ASSEMBLY [AzureLibrary];

在使用我在库中创建的函数或方法时，出现以下错误消息.

At the time of using functions or methods I created in library, I got below error message.

用户表达式的内部异常:无法加载文件或程序集'Microsoft.Azure.Management.DataLake.Store，版本= 1.0.0.0，文化=中性，PublicKeyToken = 31bf3856ad364e35'或其中之一依赖关系.该系统找不到指定的文件.当前行转储:结果:"zzz"

Inner exception from user expression: Could not load file or assembly 'Microsoft.Azure.Management.DataLake.Store, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. Current row dump: result: "zzz"

请帮助，我尝试了几种方法，但是每次都会出现相同的消息.

Please help, I tried several ways but the same message appears every time.

====================================

======================================

我正在使用以下代码

public static int DelTest() { int Retval = 1; try { var secretKey = <secret key>; var appId = <app id>; var tenantId = <tenant id>; string _adlsAccountName = <adls account name>; DataLakeStoreFileSystemManagementClient _adlsFileSystemClient; var context = new AuthenticationContext("login.windows/" + tenantId); ClientCredential clientCredential = new ClientCredential(appId, secretKey); var tokenResponse = context.AcquireTokenAsync("management.azure/", clientCredential).Result; var accessToken = tokenResponse.AccessToken; using (var client = new HttpClient()) { client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken); client.BaseAddress = new Uri("management.azure/"); // Now we can party with our HttpClient! } ServiceClientCredentials creds = new TokenCredentials(tokenResponse.AccessToken); _adlsFileSystemClient = new DataLakeStoreFileSystemManagementClient(creds); DataLakeStoreAccountManagementClient _adlsClient = new DataLakeStoreAccountManagementClient(creds); _adlsFileSystemClient.FileSystem.Delete(_adlsAccountName, "/raw_files/sls_tty_typ.txt"); } catch (Exception) { Retval = 0; throw; } return Retval; }

我使用注册程序集"进行注册

I register it using "Register Assembly"

我在U-SQL脚本中使用了以下代码

I used below code in U-SQL script

USE [master]; REFERENCE ASSEMBLY [USQLCSharpProject1]; @ext = EXTRACT result string FROM "/raw_files/test_file.txt" USING Extractors.Csv(); @ext1 = SELECT result, USQLCSharpProject1.Class1.DelTest() AS del_success FROM @ext; OUTPUT @ext1 TO "/raw_files/test_file1.txt" USING Outputters.Csv();

在执行过程中，我收到以下错误消息.

During execution, I got below error message.

请找到 packages.config 文件

<?xml version="1.0" encoding="utf-8"?> <packages> <package id="Microsoft.Azure.Management.DataLake.Analytics" version="1.0.1-preview" targetFramework="net452" /> <package id="Microsoft.Azure.Management.DataLake.Store" version="1.0.2-preview" targetFramework="net452" /> <package id="Microsoft.Azure.Management.DataLake.StoreUploader" version="1.0.0-preview" targetFramework="net452" /> <package id="Microsoft.IdentityModel.Clients.ActiveDirectory" version="3.13.8" targetFramework="net452" /> <package id="Microsoft.Rest.ClientRuntime" version="2.3.2" targetFramework="net452" /> <package id="Microsoft.Rest.ClientRuntime.Azure" version="3.3.2" targetFramework="net452" /> <package id="Newtonsoft.Json" version="6.0.8" targetFramework="net452" /> </packages>

推荐答案

对于此问题，请检查以下情况:

For this issue, Please check below scenarios:

1)确保程序集的复制本地"属性为true:

1) Make sure the assembly's property Copy Local is true:

2)在进行寄存器组装时，请确保选择了托管依赖项":

2) When Register Assembly, please make sure the Managed Dependencies are selected:

3)请检查bin/Debug文件夹以确保该程序集存在.如果寄存器大于15kb，请确保它在Data Lake存储中存在

3) please check bin/Debug folder to make sure this assembly is existed. If the register assembies larger than 15kb, please make sure it is existed in Data Lake store
