Resolution: Duplicate
> ABFS: eTag Check to mitigate Rename Failures
> --------------------------------------------
>
> Key: HADOOP-18667
> URL: https://issues.apache.org/jira/browse/HADOOP-18667
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Reporter: Sree Bhattacharyya
> Assignee: Sree Bhattacharyya
> Priority: Minor
>
> 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 temporary 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. For this, adding a check and an additional call to
> get the source eTag, in case it is not present already, to check after a
> rename retry whether the source and destination eTags match.
