steveloughran opened a new pull request, #5872:
URL: https://github.com/apache/hadoop/pull/5872
* downgrade v1 sdk to "provided"
* only allowed in one package in production code
* use isolated classes and reflection games to allow rest of module to work
without it when instantiating credential providers.
* tests updated as appropriate
* remapping of standard aws v1 credential providers to v2 classnames prior
to instantiation.

> AWS SDK v2: cut the v1 bridging support
> ---------------------------------------
>
> Key: HADOOP-18820
> URL: https://issues.apache.org/jira/browse/HADOOP-18820
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Steve Loughran
> Priority: Major
>
> The AWS SDK v2 code includes the v1 sdk core for plugin support of
> * existing credential providers
> * delegation token binding
> I propose we break #2 and rely on those who have implemented to to upgrade.
> apart from all the needless changes the v2 SDK did to the api (why?) this is
> fairly straighforward
> for #1: fix through reflection, retaining a v1 sdk dependency at test time so
> we can verify that the binder works.
