Mingliang Liu commented on HADOOP-13336:
----------------------------------------

{quote}
the complaint about an unused import is wrong: its referenced in the javado=
cs
{quote}
It happens to me a few of times. I used the full path (package) of a class =
in javadoc and removed the import statement to resolve this. Not ideal anyw=
ay.

> S3a now supports different regions, by way of declaring the endpoint =E2=
=80=94but you can't do things like read in one region, write back in anothe=
r (e.g. a distcp backup), because only one region can be specified in a con=
figuration.
> If s3a supported region declaration in the URL, e.g. s3a://b1.frankfurt s=
3a://b2.seol , then this would be possible.=20
> Swift does this with a full filesystem binding/config: endpoints, usernam=
e, etc, in the XML file. Would we need to do that much? It'd be simpler ini=
tially to use a domain suffix of a URL to set the region of a bucket from t=
he domain and have the aws library sort the details out itself, maybe with =
some config options for working with non-AWS infra
