[jira] [Created] (HADOOP-17015) ABFS: Make PUT and POST operations idempotent

Sneha Vijayarajan created HADOOP-17015:
------------------------------------------

             Summary: ABFS: Make PUT and POST operations idempotent
                 Key: HADOOP-17015
                 URL: https://issues.apache.org/jira/browse/HADOOP-17015
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/azure
    Affects Versions: 3.2.1
            Reporter: Sneha Vijayarajan
            Assignee: Sneha Vijayarajan
             Fix For: 3.4.0


Currently when a PUT or POST operation timeouts and the server has already successfully executed the operation, there is no check in driver to see if the operation did succeed or not and just retries the same operation again. This can cause driver to through invalid user errors.

 

Sample scenario:
 # Rename request times out. Though server has successfully executed the operation.
 # Driver retries rename and get source not found error.

In the scenario, driver needs to check if rename is being retried and success if source if not found, but destination is present.
