[jira] [Created] (HADOOP-18667) ABFS: eTag Check to mitigate Rename Failures

Sree Bhattacharyya created HADOOP-18667:
-------------------------------------------

             Summary: 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


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.
