> ABFS: Forced DFS Endpoint Usage Causes Failure on FNS-Blob Accounts with Soft

> Key: HADOOP-19854
> URL: https://issues.apache.org/jira/browse/HADOOP-19854
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Affects Versions: 3.5.0, 3.4.2, 3.4.3
> Reporter: Manika Joshi
> Assignee: Manika Joshi
> Priority: Major
> Labels: pull-request-available
>
> If _fs.azure.account.hns.enabled_ is not configured, ABFS driver issues a
> getAcl call +using the DFS endpoint+ to detect the account type (HNS or FNS)
> For FNS Blob accounts with Soft Delete enabled, this behavior leads to
> failures because the DFS endpoint used does not support Soft Delete semantics.
> Temporary fix is to explicitly set the configuration:
> _fs.azure.account.hns.enabled_ so the redundant DFS-based detection is
> bypassed and the issue does not occur.
