Review Comment:
sourceEtag should be passed down only for HNS account as eTag does not
remain the same when its FNS (as rename = copy to destination and delete
source).
> [ABFS]: RenameFilePath Source File Not Found (404) error in retry loop

> Key: HADOOP-18425

> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Reporter: Sree Bhattacharyya
> Assignee: Sree Bhattacharyya
> Priority: Minor
> Labels: pull-request-available
>
> RenameFilePath on its first try receives a Request timed out error with code
> 500. On retrying the same operation, a Source file not found (404) error is
> received.
> Possible mitigation: Check whether etags remain the same before and after the
> retry and accordingly send an Operation Successful result, instead of source
> file not found.
