> Using s3 rest api smaller chunks of an object could be uploaded with using Range headers:
> For example:
> {code}
> GET /example-object HTTP/1.1
> Host: example-bucket.s3.amazonaws.com
> x-amz-date: Fri, 28 Jan 2011 21:32:02 GMT
> Range: bytes=0-9
> Authorization: AWS AKIAIOSFODNN7EXAMPLE:Yxg83MZaEgh3OZ3l0rLo5RTX11o=
> Sample Response with Specified Range of the Object Bytes
> {code}
> Can be implemented with using the seek method on OzoneInputStream.
> The Range header  support is one of the missing piece for fully support s3a interface.
