DataLakeServiceClient.DeleteFileSystem() method on non-ADLSv2 upgraded storage accounts

Question

DataLakeServiceClient.DeleteFileSystem() method on non-ADLSv2 upgraded storage accounts

Anonymous

The .NET codebase I work on interacts with some storage accounts that are upgraded to ADLSv2 and some that are not. I noticed that the DataLakeServiceClient.DeleteFileSystem() method works in both cases. Can I get a confirmation that the method's behavior is the same, regardless of whether or not the storage account has been upgraded to ADLSv2?

Hi Max Morrison,
Welcome to Microsoft Q&A Forum, Thank you for posting our query here!
Yes, you are correct. The DataLakeServiceClient.DeleteFileSystem() method behaves the same regardless of whether the storage account has been upgraded to ADLSv2 or not. This method marks the specified file system for deletion, and the filesystem along with any paths contained within it are later deleted during garbage collection.

Hi, thanks for the answer. How did you verify that? I found conflicting information in the doc here:

Answer 1

Hi Max Morrison,
The note you found refers to the general support of the client library for hierarchical namespace (HNS) disabled storage accounts.
The specific method DataLakeServiceClient.DeleteFileSystem() is designed to work with both HNS-enabled and HNS-disabled accounts.

The method marks the specified file system for deletion, and this operation is supported regardless of the HNS status of the storage account. The key point is that while some advanced features of the Data Lake service require HNS to be enabled, basic operations like deleting a file system are supported in both configurations.

Please let us know if you have any further queries. I’m happy to assist you further.
