Steve Loughran created HADOOP-9261:
--------------------------------------

             Summary: S3 and S3 filesystems can move a directory under itself -and so lose data
                 Key: HADOOP-9261
                 URL: https://issues.apache.org/jira/browse/HADOOP-9261
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/s3
    Affects Versions: 2.0.2-alpha, 1.1.1
         Environment: Testing against S3 bucket stored on US West (Read after Write consistency; eventual for read-after-delete or write-after-write)
            Reporter: Steve Loughran


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.
