Do you have a jobtracker?  Without a jobtracker and tasktrackers, distcp is
running in LocalRunner mode.  I.E. it is running a single-threaded process
on the local machine.  The default behavior of the DFSClient is to write
data locally first, with replicas being placed off-rack then on-rack.

This would explain why everything seems to be going locally, it is also
probably much slower than it could be.
