Sanjay Radia updated MAPREDUCE-6040:
------------------------------------
Attachment: HDFS-6134-Distcp-cp-UseCasesTable2.pdf
Attached the distcp use cases table here for convenience.
Note distcp needs to be fixed for both superuser and normal user (see the use
case table). Row 1 and 4 in the use cases table are same for root and normal
user.
If for row 3 we believe, distcp should fail then again same for both root and
normal user.
> distcp should automatically use /.reserved/raw when run by the superuser

>
> On HDFS-6134, [~sanjay.radia] asked for distcp to automatically prepend
> /.reserved/raw if the distcp is being performed by the superuser and
> /.reserved/raw is supported by both the source and destination filesystems.
> This behavior only occurs if none of the src and target pathnames are
> /.reserved/raw.
> The -disablereservedraw flag can be used to disable this option.
