+# ABFS Driver for FNS Accounts
+
+### Note: FNS-BLOB Support is being built and not yet ready for usage.
+
+## Background
+ABFS driver is recommended to be used only with HNS Enabled ADLS Gen-2 accounts
+for big data analytics because of being more performant and scalable.
+
+However, to enable users of legacy WASB Driver to migrate to ABFS driver
without
+needing them to upgrade their general purpose V2 accounts (HNS-Disabled),
Support
+for FNS accounts is being added to ABFS driver.
+Refer to [WASB Deprication](./wasb.html) for more details.

+## Azure Service Endpoints Used by ABFS Driver
+Azure Services offers two set of endpoints for interacting with storage
accounts:
+1. [Azure Blob
Storage](https://learn.microsoft.com/en-us/rest/api/storageservices/blob-service-rest-api)
referred as Blob Endpoint
+2. [Azure Data Lake
Storage](https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/operation-groups)
referred as DFS Endpoint
+
+ABFS Driver by default is designed to work with DFS Endpoint only which

> Project: Hadoop Common

> Components: fs/azure
> Affects Versions: 3.4.0
> Reporter: Anuj Modi

>
> Azure Services support two different set of APIs.
> Blob:
> [https://learn.microsoft.com/en-us/rest/api/storageservices/blob-service-rest-api]

> DFS:
> [https://learn.microsoft.com/en-us/rest/api/storageservices/datalakestoragegen2/operation-groups]
>
> As per the plan in HADOOP-19179, this task enables ABFS Driver to work with
> both set of APIs as per the requirement.
> Scope of this task is to refactor the ABfsClient so that ABFSStore can choose
> to interact with the client it wants based on the endpoint configured by user.
> The blob endpoint support will remain "Unsupported" until the whole code is
> checked-in and well tested.
