While trying to use hadoop as a HDFS datanode on Windows, I ran into it
trying to use DU and excepting because it couldn't find it.  The Hadoop FAQ
claims that one can run Hadoop in just the Windows command prompt.  Does
HDFS have different constraints/need other stuff in order to actually make
use of Cygwin?

Hadoop requires a reasonable cygwin environment. bash, du, whoami, and
the various coreutils and fileutils are all required.

Which FAQ do you read?
This one
http://wiki.apache.org/hadoop/FAQ#2
says
"Windows requires the installation of Cygwin"

Should have been more explicit.  I meant inside a Windows command prompt
instead of the cygwin bash shell.  Figured out the problem, it was a path
problem due to HDFS running as a service and thus not seeing the user
environment symbols pointing towards cygwin.
