+[~snehav]
> Unable to use custom SAS tokens for accessing files from ADLS gen2 storage

> Key: HADOOP-17879
> URL: https://issues.apache.org/jira/browse/HADOOP-17879
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure, tools
> Reporter: Arun Ravi M V
> Priority: Major
>
> I have some parquet files in abfss://[email protected]/folder1/.
> I generated the User Delegation SAS token with the following permission on
> 'folder1'
> SAS_SIGNED_PERMISSIONS -> "racwdxltmeop"
> But when I read from "abfss://[email protected]/folder1/"
> I get a *HTTP 403 error*, I believe this happens when ABFSS driver makes use
> of `*getACLStatus*` API call to determine whether the storage service has
> hierarchical namespace enabled or not.
>
> I found a workaround, ie to set *fs.azure.account.hns.enabled* to *true*
> which would skip get ACL API call and as folder level SAS only works for HNS
> enabled accounts. May I know if this behavior is expected and the workaround
> I am using is stable for production use and if there are any hidden
> implications?
>
> Thank you in advance.
