             Summary: Support virtual-hosted style URLs
                 Key: HDDS-525
                 URL: https://issues.apache.org/jira/browse/HDDS-525
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
            Reporter: Elek, Marton


AWS supports to kind of pattern for the base url of the s3 rest api: 
virtual-hosted style and path-style.

Path style: http://s3.us-east-2.amazonaws.com/bucket
Virtual-hosted style: http://bucket.s3.us-east-2.amazonaws.com

By default we support the path style method with the volume name in the url:

http://s3.us-east-2.amazonaws.com/volume/bucket

Here the endpoint url is http://s3.us-east-2.amazonaws.com/volume/ and the 
bucket is appended.

Some of the 3rd party s3 tools (goofys is an example) Supports only the virtual 
style method. With goofys we can set a custom endpoint (http://localhost:9878) 
but all the other postfixes after the port are removed.

It can be solved with using virtual-style url which also could include the 
volume name:

http://bucket.volume..........com

The easiest way is to support both of them is implementing a 
ContainerRequestFilter which can parse the hostname (based on a configuration 
value) and extend the existing url with adding the missing volume/bucket part.
