Azure Data Lake Storage Gen2: implementing Hierarchical Namespace and File Access Permissions
I'm trying to debug I'm working on a project and hit a roadblock. I'm collaborating on a project where I'm currently working on an Azure Data Lake Storage Gen2 setup where I need to enable a hierarchical namespace to effectively manage my files... I've enabled the hierarchical namespace as per the Azure documentation, but I'm running into issues with file access permissions. After creating a container and uploading files, I set the access control to allow my Azure function app to read from the storage account. However, when the function tries to access the files, I get the following behavior: `403 Forbidden - The user does not have permission to perform this action.` I've double-checked the role assignments, and the function app's managed identity has been granted 'Storage Blob Data Reader' role at the container level. Here's a snippet of how I'm trying to access the files in my Azure function: ```csharp using Azure.Storage.Files.DataLake; var serviceClient = new DataLakeServiceClient("<your_connection_string>"); var fileSystemClient = serviceClient.GetFileSystemClient("<your_file_system>"); var directoryClient = fileSystemClient.GetDirectoryClient("<your_directory>"); var fileClient = directoryClient.GetFileClient("<your_file_name>"); var fileContents = await fileClient.ReadAsync(); ``` I've also confirmed that the networking settings on the storage account allow access from the Azure function's subnet. I've tried reassigning the managed identity and even granting broader permissions temporarily, but nothing seems to resolve the scenario. Is there something I'm missing regarding hierarchical namespace configurations or permissions that might be causing this access scenario? I'd appreciate any insights or suggestions on how to troubleshoot this further. This is part of a larger application I'm building. This is for a application running on Windows 10. Is there a simpler solution I'm overlooking? I'm working on a service that needs to handle this. Cheers for any assistance!
