given that the feature has never worked properly through MR/spark jobs *and*
nobody has ever filed a bug report against the feature, I'm not sure it gets
used *at all*.
we should be ruthless here; cut it?
> AWS SDK v2: make the v1 bridging support optional
> -------------------------------------------------
>
> 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
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
>
> 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.
