---------------------------------------
bq. trashing .... It's assumed that an hdfs admin would not (intentionally) do
that.
Okay, please add that your doc when you next update it. We could allow just
read access to /r/r/ to all.
Use cases: charles can we please work together to get the distcp use cases
nailed. We can work offline to go faster and then summarize for the community.

> 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.
