DF is the only win-incompatibility if you can run your cluster without
scripts.
There is a version of DF.java source file that is compatible with windows.
http://issues.apache.org/jira/secure/attachment/12337494/DF.java
Just replace your df.java with this, recompile, and you don't need to
run cygwin.
See also HADOOP-33.
It is good to know that in Java 6 the df problem is solved.

hi,all:
As we known , now hadoop can't run on windows because of the
unix shell used by ant and DF utility used by DF.java ,I think the
unix shell could be easyly replace with java code or ant script ,And
in Java 6, I find the DF utility can be replace with
getUsableSpace() and getTotalSpace() of java.io.File. Between the
two, you can show how much space
each file system has available and has in total(See the code listed
below). May be the DF class should made to more smart to support
different OS and JDK .
Actually, Hadoop runs fine on Windows, except when someone makes a
mistake. *smile* Under Windows, it requires cygwin. I just updated
the FAQ to include the platform information:
http://wiki.apache.org/lucene-hadoop/FAQ
Java 6 has just been released and I think it is too early to make
Hadoop require Java 6 in order to run. Of course in the long run,
having a pure Java implementation of all of the required
functionality is a very good thing.
