Review Comment:
   Is this meant to say "...set to trace.."? The if statement is looking for 
trace.

>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: build, fs/s3
>    Affects Versions: 3.4.2
>            Reporter: Steve Loughran

> This SDK update doesn't need to come with some changes to disable some new 
> features (default integrity protections),
> and to apply critical changes related to the SDK
> Default integrity protection came with 2.30, and is on unless disabled.
> https://github.com/aws/aws-sdk-java-v2/issues/5801
> As well as being incompatible with third party stores, it has also affected 
> S3 multiregion Access Points: 
> https://github.com/aws/aws-sdk-java-v2/issues/5878
> This has broken most interaction with third party stores, hence fixes in 
> Iceberg https://github.com/apache/iceberg/pull/12264 and Trinio 
> https://github.com/trinodb/trino/pull/24954
> There's also [AWS v2.30 SDK InputStream behavior changes #5859](AWS v2.30 SDK 
> InputStream behavior changes).
> It looks like our code is safer from that, but it did require code review.
> SDK 2.30.19 seems good with this
