URL: https://github.com/apache/hadoop/pull/8306#issuecomment-4292896877
Follow-up push for the latest javadoc artifact: the remaining new warning
was on CUSTOM_REQUEST_HEADERS_S3_PREFIX because the added @value tag is not
valid on that derived String constant. I removed that tag and force-pushed the
updated single commit. The exact module-level javadoc command is still not
reproducible locally here because standalone hadoop-aws resolution needs
snapshot artifacts that are not available from apache.snapshots in this
environment, but the targeted AWS tests from the earlier push still passed
locally: TestAwsClientConfig and TestRequestFactory (20 tests, 0 failures).
> Allow to skip recursive file deletion for non-empty directory

> Key: HADOOP-19801
> URL: https://issues.apache.org/jira/browse/HADOOP-19801
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs/s3
> Reporter: Enrico Minack
> Priority: Major
> Labels: pull-request-available
>
> A non-empty directory, as well as a directory where its emptiness is unknown,
> is deleted by listing all contained files (or objects with matching key
> prefix), then deleting those files (objects) in bulk delete requests, and
> finally deleting the (then) empty directory itself.
> The recursive deletion of objects is not needed for S3 endpoints that support
> deleting non-empty directories (or path prefixes).
> For example: The [VAST S3 endpoint supports deleting non-empty
> directories|https://kb.vastdata.com/documentation/docs/using-trash-folder-for-s3-objects-6]
> with a single request. Such a feature can only be fully leveraged if
> {{hadoop-aws}} coupd skip the recursive deletion.
