Unlike version 1 of the S3 List Objects API, version 2 by default does not fetch object owner information, which S3A doesn't need anyway. By switching to v2, there will be less data to transfer/process. Also, it should be more robust when listing a versioned bucket with "a large number of delete markers" (according to AWS).
Methods in S3AFileSystem that use this API include:
- innerDelete(Path, boolean)
- innerRename(Path, Path)
Requires AWS SDK 1.10.75 or later.
