Review Comment:
This is now also importing all the http status code constants (e.g.
`InternalConstants.SC_404_NOT_FOUND`).
> Upgrade AWS SDK to v2
> ---------------------
>
> Key: HADOOP-18073
> URL: https://issues.apache.org/jira/browse/HADOOP-18073
> Project: Hadoop Common
> Issue Type: Task
> Components: auth, fs/s3
> Affects Versions: 3.3.1
> Reporter: xiaowei sun
> Assignee: Ahmar Suhail
> Priority: Major
> Labels: pull-request-available
> Attachments: Upgrading S3A to SDKV2.pdf
>
>
> This task tracks upgrading Hadoop's AWS connector S3A from AWS SDK for Java
> V1 to AWS SDK for Java V2.
> Original use case:
> {quote}We would like to access s3 with AWS SSO, which is supported in
> software.amazon.awssdk:sdk-core:2.*.
> In particular, from
> [https://hadoop.apache.org/docs/stable/hadoop-aws/tools/hadoop-aws/index.html],
> when to set 'fs.s3a.aws.credentials.provider', it must be
> "com.amazonaws.auth.AWSCredentialsProvider". We would like to support
> "software.amazon.awssdk.auth.credentials.ProfileCredentialsProvider" which
> supports AWS SSO, so users only need to authenticate once.
> {quote}
