问题描述

我正在尝试使用以下命令访问datalake文件夹中的文件:

I am trying to access the files in datalake folder with command:

Get-AzureRmDataLakeStoreChildItem -AccountName $ dataLakeStorageGen1Name -Path $ myrootdir

Get-AzureRmDataLakeStoreChildItem -AccountName $dataLakeStorageGen1Name -Path $myrootdir

但这给出了以下内容 错误.如何解决此问题?

But it gives the below mentioned error. how can I fix this issue?

Get-AzureRmDataLakeStoreChildItem:在获取路径/dummy之后的listStatus时出错

推荐答案

哈哈，

您遇到令牌问题:

Please check that this managed service is configured to emit tokens at this address and that the associated managed service identity has the appropriate role assignment and try logging in again.,Token Length is 6. Something is wrong with the token.]

在这种情况下，您需要首先通过传递Connect-AzureRmAccount cmdlet来向Azure进行身份验证，然后运行所需的cmdlet:

In this scenario, you need to authenticate with Azure first by passing the Connect-AzureRmAccount cmdlet first and then run your desired cmdlet: Get-AzureRmDataLakeStoreChildItem
-AccountName

dataLakeStorageGen1Name -Path

dataLakeStorageGen1Name -Path

myrootdir

myrootdir

登录使用Azure PowerShell 或者，如果您想使用REST API，则还有另一种身份验证方法: 使用REST API使用Azure Data Lake Storage Gen1进行最终用户身份验证

Or, if you are wanting to use the REST API, there is another authentication method: End-user authentication with Azure Data Lake Storage Gen1 using REST API

您是否可以运行此cmdlet来确保正确设置了帐户:

Can you run this cmdlet to ensure the account is set up correctly:

Test-AzureRmDataLakeStoreAccount-名称

Test-AzureRmDataLakeStoreAccount -Name
