Timur Alperovich commented on JCLOUDS-1213:
-------------------------------------------

I'm running into a similar problem when attempting to list contents of a 
non-US-Standard bucket.

Here is the simple failing example (fails with jclouds 2.0.0):
{code}
public class TestMain {
    public static void main(String[] args) throws Exception {
        BlobStoreContext context = ContextBuilder.newBuilder("aws-s3")
                .credentials("AWS-ACCESS-KEY-ID", "SECRET-ACCESS-KEY")
                .buildView(BlobStoreContext.class);
        BlobStore blobStore = context.getBlobStore();
        for (StorageMetadata meta: blobStore.list("EU-West-1-Bucket")) {
            System.out.println(meta.getName());
        }
    }
}
{code}

The resulting error is:
{{message='The authorization header is malformed; the region 'us-east-1' is 
wrong; expecting 'eu-west-1''}}

I suspect jclouds needs to check the bucket location before submitting the 
request. I haven't figured out how to express that.

> When using a BlobStore configured for the 'aws-s3' provider and with an 
> explicit region ('eu-west-1' in this case), 
> _BlobStore.createContainerInLocation(Location location, String container)_ 
> fails with a 400 when attempting to create an already existing bucket on that 
> location.
> The error message from AWS claims the cause to be 
> _AuthorizationHeaderMalformed_, and says that 'eu-west-1' was expected, but 
> that 'us-east-1' was supplied in the PUT request.
> I have confirmed that 'eu-west-1' is, in fact, given to the method call, but 
> it does not seem to be respected when forming and signing the request.
> This does not happen on 1.9.x.
> From the debugging i have done a likely culprit seems to be 
> _Aws4SignerForAuthorizationHeader_ which resolves a _ServiceAndRegion_ 
> instance, which in turn seem to attempt parsing the region from the hostname 
> URL (_AWSHostNameUtils.parseRegionName(..)_). I cannot see the region set for 
> the provider being respected in this case.
