>                 Key: HADOOP-16370
>                 URL: https://issues.apache.org/jira/browse/HADOOP-16370
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/s3
>    Affects Versions: 3.3.0
>            Reporter: Steve Loughran
>            Priority: Minor
>
> Something to consider if we want: should the etag and version from the 
> initial getObjectMetadata call be propagated to the actual CopyRequest *if 
> they are not already known*
> That way, if we rename() a file and its etag/version is not known, we can fix 
> them for the next stage of the operation. Relevant given we are copying 
> metadata over, and for resilience to changes while the copy is taking place
