Steve Loughran commented on HADOOP-13336:
-----------------------------------------
OK, thanks for the vote. Can I be the one to (carefully) commit this. I plan to
# commit to trunk & branch-2
# merge trunk into the s3guard branch
# apply the bits of the the patch for the s3guard branch which aren't in the trunk branch
That way, I can get into the mainline branches a feature that is needed for many things (primarily
cross v4 auth site and to use different credentials without embedding secrets in URIs), without
creating merge pain downstream.

> 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
