> [ABFS] Rename/Create path idempotency client-level resolution
> -------------------------------------------------------------
>
> Key: HADOOP-19450
> URL: https://issues.apache.org/jira/browse/HADOOP-19450
> Project: Hadoop Common
> Issue Type: Task
> Components: fs/azure
> Affects Versions: 3.5.0
> Reporter: Manish Bhatt
> Assignee: Manish Bhatt
> Priority: Major
> Labels: pull-request-available
>
> CreatePath and RenamePath APIs are idempotent as subsequent retries on same
> resource don’t change the server state. However, when client experiences
> connection break on the CreatePath and the RenamePath APIs, client cannot
> make sense if the request is accepted by the server or not.
> On connection failure, the client retries the request. The server might
> return 404 (sourceNotFound) in case of RenamePath API and 409
> (pathAlreadyExists) in case of CreatePath (overwrite=false) API. Now the
> client doesn’t have a path forward. Reason being, in case of CreatePath,
> client doesn’t know if the path was created on the original request or the
> path was already there for some other request, in case of RenamePath, client
> doesn’t know if the source was removed because of the original-try or it was
> not there on the first place.
