>                 Key: HADOOP-19588
>                 URL: https://issues.apache.org/jira/browse/HADOOP-19588
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: fs/s3
>            Reporter: Revathi Vijay
>            Priority: Major
>   Original Estimate: 336h
>  Remaining Estimate: 336h

> * Currently, the endpoint for using S3 accesspoint is resolved for S3 and S3 
> on outposts: 
> https://github.com/apache/hadoop/blob/trunk/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/ArnResource.java#L29-L30.
>  However, for s3express, the endpoint is 
> "s3express-<zoneId>.<region>.amazonaws.com". 
> (https://docs.aws.amazon.com/AmazonS3/latest/userguide/directory-bucket-az-networking.html).
>  This ticket adds support for s3express endpoint.
> * Additionally, for access objects using s3express in the `S3AFileSystem`, we 
> need to parse the access point ARN for an S3express access point into the 
> access point name, since ARNs aren't supported on S3express other than in IAM 
> policies. 
> (https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-points-directory-buckets-restrictions-limitations-naming-rules.html).
>  This ticket also addresses this change.
> * This ticket also updates the SDK version used by the changes to `2.31.12`, 
> which is the version (at minimum) needed to use s3express access points. It 
> does not do the SDK upgrade, but only the version of the dependency.
