Parent: HADOOP-19353 (was: HADOOP-18477)
> S3A Xattr headers need hdfs-compatible prefix
> ---------------------------------------------
>
> Key: HADOOP-19176
> URL: https://issues.apache.org/jira/browse/HADOOP-19176
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0, 3.3.6
> Reporter: Steve Loughran
> Priority: Major
>
> x3a xattr list needs a prefix compatible with hdfs or existing code which
> tries to copy attributes between stores can break
> we need a prefix of {user/trusted/security/system/raw}.
> now, problem: currently xattrs are used by the magic committer to propagate
> file size progress; renaming the prefix will break existing code. But as it's
> read only we could modify spark to look for both old and new values.
> {code}
