Is "chmod" in your path?

hello there,

first of all thanks for the response.
The wiki doesn't say where the .jar sould be, but the maven script doesn't create it anywhere. I am guessing it's because the test fails but i have no 
idea (it compiles just fine).

I'll try installing Cywing, In the meantime the stack trace:

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
Tests run: 16, Failures: 0, Errors: 4, Skipped: 0, Time elapsed:
4.266 sec
<<< FAILURE!

Running org.apache.mahout.clustering.kmeans.TestKmeansClustering
Tests run: 5, Failures: 0, Errors: 1, Skipped: 0, Time elapsed:
1.156 sec
<<< 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?


Can you give more of the stack trace?  I haven't run on Windows, but
by the looks of it you need to have "chmod" in your path, which likely means you need to have Cygwin or something similar installed. This is 
likely a Hadoop issue on Windows, but please post more so we can
confirm.




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?


Hopefully, http://cwiki.apache.org/MAHOUT/buildingmahout.html should
help.



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.



Cool!
