> S3A: Support S3 Conditional Writes
> ----------------------------------
>
> Key: HADOOP-19256
> URL: https://issues.apache.org/jira/browse/HADOOP-19256
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Ahmar Suhail
> Priority: Major
> Labels: pull-request-available
>
> S3 Conditional Write (Put-if-absent) capability is now generally available -
> [https://aws.amazon.com/about-aws/whats-new/2024/08/amazon-s3-conditional-writes/]
>
> S3A should allow passing in this put-if-absent header to prevent over writing
> of files.
> There is a feature branch for this: HADOOP-19256-s3-conditional-writes
> + support etags to allow an overwrite to be restricted to overwriting a
> specific version. This can be done through a createFile option.
> https://docs.aws.amazon.com/AmazonS3/latest/userguide/conditional-writes.html
> Fun fact; third party stores will not reject overwrites if they don't
> recognise the headers, so there's no way to be sure they are supported
> without testing.
> we need a flag to enable/disable conditional writes which can be exposed in a
> hasPathCapability()
