---------------------------------------
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
