Steve Loughran commented on HADOOP-13892:
-----------------------------------------
Given the need for xattrs, for full distcp we really need distcp itself to
downgrade and persist the attr data as some explicitly created file alongside
the data, e.g
{code}
/path/file1.avro
/path/file1.avro.xattr
{code}
Going to close this as a wontfix
> use s3 tags/headers 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
> Priority: Major
>
> 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.
