Unable to find KMeans Cluster class

Hi,

I have following code snippet from the book 'Hadoop in Action':

Vector vec = vectors.get(i);
Cluster cluster = new Cluster(vec, i, new EuclideanDistanceMeasure());

I am unable to find Cluster class anywhere with constructor as above. In 
fact under package
org.apache.mahout.clustering Cluster is defined as an interface and not 
as a class.

Is there any version mismatch or something? Or I need to import Cluster 
class from some other package that I am not aware of?

Thanks,
Abhinav M Kulkarni

Okay, I used Kluster class under org.apache.mahout.clustering.kmeans 
package. This implements interface Cluster.

That may be a typo in the book. I don't know if it was non-abstract in the
past. But try against version 0.5 to be sure. I don't know what the
replacement code is if so but someone else here likely does.
