Description

Using s3 rest api smaller chunks of an object could be uploaded with using Range headers:

For example:

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

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.
