Description

Refer to the doc attached to HDFS-6509 for background.

Like distcp -p (see MAPREDUCE-6007), the copy command also needs to preserve extended attributes in the raw.* namespace by default whenever the src and target are in /.reserved/raw. To not preserve raw xattrs, don't specify /.reserved/raw in either the src or target.
