--------------------------------------------------------------------
My question is why is any explicit configuration needed for alias?
The two ways for a customer to configure their S3 Access Point would be:
* Configure {{fs.s3a.bucket.%s.accesspoint.arn}} to specify that a particular
bucket should route via that S3 Access Point
* Configure their Hadoop file system using the S3 Access Point alias as the
bucket name. Do not configure {{{}fs.s3a.bucket.%s.accesspoint.arn{}}}.
We may need to add some tests for using alias in place of bucket. Things like
delegation tokens may be a little fragile assuming the bucket is a real bucket.

> Support S3 access point alias

> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.4
> Reporter: Shen Cong
> Priority: Major
>
> Adding support for using access point alias to access s3 bucket.
>
> When you create an access point, Amazon S3 automatically generates an alias
> that you can use instead of an Amazon S3 bucket name for data access. You can
> use this access point alias instead of an Amazon Resource Name (ARN) for any
> access point data plane operation.
