Frank Scholten updated MAHOUT-564:
----------------------------------
Attachment: MAHOUT-564.patch
Adds a computeConvergence method to KMeansClusterer which does use the
distanceThreshold. Includes unit test.
> KMeansClusterer does not use distanceThreshold parameter in
> testConvergence(Iterable<Cluster> clusters, double distanceThreshold) method

>
> While running KMeansClusterer#runKMeansIteration sequentially I noticed that
> the distanceThreshold parameter is not used. The convergenceDelta field is
> used instead. However, it's initialized at 0 and only set when creating a
> KMeansClusterer with a Configuration object, which is only used in a
> MapReduce setting.
