Sean Owen commented on MAHOUT-564:
----------------------------------
I'm cleaning house on some issues that have stalled -- this look ready-ish to
commit.
But I get an error in the test when I apply it:
java.lang.AssertionError: Cluster 1 test 3 expected:<4> but was:<5>
at org.junit.Assert.fail(Assert.java:91)
at org.junit.Assert.failNotEquals(Assert.java:645)
at org.junit.Assert.assertEquals(Assert.java:126)
at org.junit.Assert.assertEquals(Assert.java:470)
at
org.apache.mahout.clustering.kmeans.TestKmeansClustering.testReferenceImplementation(TestKmeansClustering.java:150)

ideas?

> 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.
