---------------------------------------------------
Hi Peter, I am not saying that your patch is breaking anything. I mean that
when RawLocalFileStatus is created, it is known that RawLocalFileStatus would
break DistCp.FilePair.
It seems that your patch is not generated from trunk since the line numbers do
not match. Could you generate a new patch from trunk?
> DistCp cannot handle -delete if destination is local filesystem
