             Summary: S3A: add option to disable probe for dir marker recreation on delete/rename.
                 Key: HADOOP-18544
                 URL: https://issues.apache.org/jira/browse/HADOOP-18544
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.3.4
            Reporter: Steve Loughran
            Assignee: Harshit Gupta


In applications which do many single-file deletions on the same dir, a lot of time is wasted in {{maybeCreateFakeParentDirectory()}}.

Proposed: add an option to disable the probe, for use by applications which are happy for parent dirs to sometimes disappear after a cleanup.

file by file delete is still woefully inefficient because of the HEAD request on every file, but there's no need to amplify the damage.
