>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs/s3
>    Affects Versions: 1.1.1, 2.0.2-alpha
>         Environment: Testing against S3 bucket stored on US West (Read after Write consistency; eventual for read-after-delete or write-after-write)

> In the S3 filesystem clients, {{rename()}} doesn't make sure that the destination directory is not a child or other descendant of the source directory. The files are copied to the new destination, then the source directory is recursively deleted, so losing data.
