> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Blocker
>
> The patch in HADOOP-16490 is incomplete: we are still checking for the Head
> of each object, even though we only wanted the directory checks. As a result,
> createFile is still vulnerable to 404 caching on unguarded S3 repos.
