I just did a clean and an update and ran "mvn install" and all tests
pass for me.
I'm running JDK 1.6 on OS X (latest) with Maven 2.0.10.
You can skip the tests in Maven by passing in -DskipTests=true
However, it makes me wonder what's going wrong and whether it will work.
Note, also, we have been reworking some of the clustering stuff
internals, so maybe you happened to get a copy of trunk at the wrong
time.

Hey Bill,
I've been having problems w/ the Bayesian examples too, but not
enough time to look into them. However, that is about to change and
will be digging into it a bit more early next week or this weekend.
I will note a couple of things. I've seen some reports of problems
w/ Maven 2.1.0 not working on Mahout. Also, I believe the trunk
version requires Hadoop 0.19.1, but check the POM to be sure.
In the meantime, any insight you have is appreciated.

I am using the 0.1 release tar ball and the Hadoop job files

results are not correct. Here is the output I got:

I am getting the same results for both Bayes and CBayes. Any idea
what I am
doing wrong?
I also want to run the example using the trunk so I checked it out
and ran
"mvn install". I found that the Hadoop job files are not being
created due
to a test failure:
Running org.apache.mahout.clustering.kmeans.TestKmeansClustering

I am not sure how to fix this. Is there anyway to build the Hadoop
job
files without running the tests?
By the way, I am using maven 2.1.0 and Hadoop 0.18.3.
