Chris Nauroth commented on HADOOP-13336:
----------------------------------------
bq. What I'm thinking of here is allowing you to override all global options
with per-bucket values;
+1. I've had some other use cases in mind for this too:
* Different endpoint settings.
* Different TCP connection management settings and multi-part settings for a
process co-located in the same AWS region as one bucket but not the other.
* Different User-Agent customization within the same process.
* Server-side encryption on one bucket but not the other.
Thanks for coming up with a generalized configuration idea.

> 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
> Priority: Minor
>
> 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
