[jira] [Created] (HADOOP-13336) support cross-region operations in S3a

Steve Loughran created HADOOP-13336:
---------------------------------------

             Summary: support cross-region operations in S3a
                 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
