Steve Loughran commented on HADOOP-13336:
-----------------------------------------
ps, you know that once you start declaring your own auth chain, we take away
the ability to use id:secret in URIs. It's just near-impossible to keep those
secrets out the logs, despite all the effort in HADOOP-3733. sticking your
secrets in URIs is just a way to lose your data and your money

> Key: HADOOP-13336
> URL: https://issues.apache.org/jira/browse/HADOOP-13336
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
>
> S3a now supports different regions, by way of declaring the endpoint —but you
> can't do things like read in one region, write back in another (e.g. a distcp
> backup), because only one region can be specified in a configuration.
> If s3a supported region declaration in the URL, e.g. s3a://b1.frankfurt
> s3a://b2.seol , then this would be possible.
> Swift does this with a full filesystem binding/config: endpoints, username,
> etc, in the XML file. Would we need to do that much? It'd be simpler
> initially to use a domain suffix of a URL to set the region of a bucket from
> the domain and have the aws library sort the details out itself, maybe with
> some config options for working with non-AWS infra
