[jira] [Created] (HADOOP-13892) use s3 to record permissions on objects, so preserving them through distcp round trips

---------------------------------------

             Summary: use s3 to record permissions on objects, so preserving them through distcp round trips
                 Key: HADOOP-13892
                 URL: https://issues.apache.org/jira/browse/HADOOP-13892
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 2.9.0
            Reporter: Steve Loughran


S3 now supports object tags, attributes which can be updated during the life of an object.

S3A could use that to preserve the permissions/ACLs of objects when copied from elsewhere, in particular from HDFS. This would ensure that data backed up from HDFS preserves all the permission information needed when doing a recovery from S3 to HDFS.

Azure WASB does exactly this already.
