URL: https://github.com/apache/hadoop/pull/5485

   
   If "fs.azure.enable.rename.resilience" is true, then do a HEAD of the source 
file before the rename, which can then be used to recover from the failure, as
   the manifest committer does (HADOOP-18163).

> [ABFS]: RenameFilePath Source File Not Found (404) error in retry loop

>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs/azure
>            Reporter: 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 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.
