> ABFS: Enable config controlled ETag check for Rename idempotency
> ----------------------------------------------------------------
>
> Key: HADOOP-18012
> URL: https://issues.apache.org/jira/browse/HADOOP-18012
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.3.2
> Reporter: Sneha Vijayarajan
> Assignee: Sree Bhattacharyya
> Priority: Major
> Labels: pull-request-available
>
> ABFS driver has a handling for rename idempotency which relies on LMT of the
> destination file to conclude if the rename was successful or not when source
> file is absent and if the rename request had entered retry loop.
> This handling is incorrect as LMT of the destination does not change on
> rename.
> This Jira will track the change to undo the current implementation and add a
> new one where for an incoming rename operation, source file eTag is fetched
> first and then rename is done only if eTag matches for the source file.
> As this is going to be a costly operation given an extra HEAD request is
> added to each rename, this implementation will be guarded over a config and
> can enabled by customers who have workloads that do multiple renames.
> Long term plan to handle rename idempotency without HEAD request is being
> discussed.
