I do not believe that the Mahout code itself requires Cygwin. Hadoop
requires it on Windows boxes so that it can issue e.g. chmod commands to
a uniform OS interface. Our unit tests utilize Hadoop to test their
parallel versions and, if Cygwin is not installed, those tests will fail
and the jar will not be built. You will have the same problem running
any of the parallel versions on a Windows box without Cygwin.
Is there an issue with using Cygwin?

I had the same problem.
Then I got to trying it with cygwin. My errors came down from 3 to 1 and
after that I just gave up.

Ok,
my question is: Is there anyway to create the .jar without the Cygwin? (all
the exceptions are in parts of the framework i won't use)
Does that mean mahout doesn't have a Windows version?
Sorry for the silly questions again.

Hi guys,
i am trying to compile mahout using Netbeans. Installed the plugins and
everything seems to work fine and I am able to compile the whole thing.
However, some tests have errors, exceptions that are not correctly
handled
(and this seems to prevent the .jar file to be created for the Mahout
core
target of the pom file - i am not familiar with maven :S)
The tests that are getting errors are:
Running org.apache.mahout.ga.watchmaker.MahoutEvaluatorTest
Tests run: 2, Failures: 0, Errors: 2, Skipped: 0, Time elapsed: 1.093 sec
<<< FAILURE!
Running org.apache.mahout.clustering.dirichlet.TestMapReduce

sec
<<< FAILURE!
Running org.apache.mahout.clustering.kmeans.TestKmeansClustering

<<< FAILURE!
Running org.apache.mahout.clustering.meanshift.TestMeanShift
Tests run: 4, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 2.203 sec
<<< FAILURE!
I am getting the following exception:
java.io.IOException: Cannot run program "chmod": CreateProcess error=2, O
sistema não pode encontrar o arquivo especificado (The system can't find
the specified file)
Does this have anything to do with the fact that i am trying to run it on
Windows?
How do I get it to work (and generate the .jar file so i can run the
samples)? the .jar file should be in the mahout\core\build folder after
build, right?
Sorry for the silly question, i am just trying to get this to work. We
have a bayesian decision system that using Netica-J and I am looking for
alternatives.
