---------------------------------------
Summary: Switch to v2 of the S3 List Objects API in S3A
Key: HADOOP-13421
URL: https://issues.apache.org/jira/browse/HADOOP-13421
Project: Hadoop Common
Issue Type: Improvement
Components: fs/s3
Affects Versions: 2.8.0
Reporter: Steven K. Wong
Priority: Minor
Unlike [version
1|http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketGET.html] of the S3
List Objects API, [version
2|http://docs.aws.amazon.com/AmazonS3/latest/API/v2-RESTBucketGET.html] 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. Methods in
S3AFileSystem that use this API include:
* getFileStatus(Path)
* innerDelete(Path, boolean)
* innerListStatus(Path)
* innerRename(Path, Path)
Requires AWS SDK 1.10.75 or later.
