使用参考组件时出现U-SQL错误 [英] U-SQL Error while using REFERENCE ASSEMBLY
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("https://login.windows.net/" + tenantId);
ClientCredential clientCredential = new ClientCredential(appId, secretKey);
var tokenResponse = context.AcquireTokenAsync("https://management.azure.com/", clientCredential).Result;
var accessToken = tokenResponse.AccessToken;
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);
client.BaseAddress = new Uri("https://management.azure.com/");
// 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

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
