> S3A: Upgrade AWS V2 SDK to 2.29.52
> ----------------------------------
>
> Key: HADOOP-19485
> URL: https://issues.apache.org/jira/browse/HADOOP-19485
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: build, fs/s3
> Affects Versions: 3.4.2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
>
> Upgrade to 2.29.52 -the last version compatible with third party stores until
> there are fixes in the AWS SDK or workarounds added in the S3A connector
> 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
