> Key: HDDS-9680
> URL: https://issues.apache.org/jira/browse/HDDS-9680
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Manager, S3
> Affects Versions: 1.4.0
> Reporter: Vyacheslav Tutrinov

> Priority: Major
> Labels: pull-request-available
>
> In the scope of HDDS-9114 and HDDS-9115 a support of 'ETag' was implemented.
> But for the parts of multipart uploaded keys the implementation wasn't
> changed - the ETag refers to the part's key path and it's not an md5 hash of
> its content.
> It means that another part (e.g. on rewriting the big key) can have the same
> path (aka 'ETag') but its content can differ from the previous one, it
> follows that the 'ETag' property of the part should differ too which is not
> true in the described case.
> The improvement should provide a way of computing the parts' paths based on
> md5-calculated ETags on commiting the multipart upload operation
