Summary: Support Range header for Oozne s3 object download
Key: HDDS-791
URL: https://issues.apache.org/jira/browse/HDDS-791
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Components: S3
Reporter: Elek, Marton
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.
