------------------------------------------
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.
