> Key: HDDS-15259

> Project: Apache Ozone
> Issue Type: Sub-task

> Priority: Major
>
> This JIRA addresses two core compliance issues in the *object tagging*
> implementation:
> # *Overwrite vs. Merge:* Currently, tagging operations appear to be merging
> new tags with existing ones. AWS S3 specification requires that
> {{PutObjectTagging}} completely replaces the existing tag set with the new
> one provided in the request. This causes {{test_put_modify_tags on ceph}} to
> fail.
> # *Empty Value Support:* The S3 Gateway validator currently rejects tags
> with an empty value string (e.g., {{{}Key=TagA, Value={}}}) with an
> {{InvalidTag}} error. AWS S3 permits keys to have empty string values. This
> causes {{test_put_obj_with_tags}} to fail.
> *Proposed Fix:*
> 1. Update the internal tagging logic to ensure {{*setTags()*}} is called
> instead of an additive operation, ensuring a full overwrite of the metadata.
> 2. Update *{{validateAndGetTagging()}}* in {{EndpointBase}} to allow values
> with zero length when x-amz-tagging header is present else on normal put
> object tagging this null tag value should fail, while maintaining the
> requirement that the Key must have at least one character.
