---------------------------------------
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.
