Steve Loughran commented on HADOOP-13336:
-----------------------------------------
note we don't need to change existing URIs, just new ones, if they have a
different config from the default. Use the default values, you get what's
normal. It's just no longer transparent what you've got
Oh, one little issue: on 2.7-2.8, if you include a user in the authority, but
no password, e.g. no : or details, you just get login information ignored
silently. We may want to urgently change 2.8 and 2.7.x to fail here, even
before we settle on what a good config policy is.
> S3A to support per-bucket configuration
> ---------------------------------------
>
> 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
