---------------------------------------
Summary: S3Guard ProgressiveRenameTracker to mark dest dir as
authoritative on success
Key: HADOOP-16474
URL: https://issues.apache.org/jira/browse/HADOOP-16474
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.3.0
Reporter: Steve Loughran
After a directory rename is successful, the destination will contain only those
files which have been copied by the S3guard-enabled client, with the directory
tree updated as new entries are added.
At that point, the ProgressiveRenameTracker could tell the store to complete
the rename and in so doing, give clients maximum performance without needing
any LIST commands.
