Trying it out, found one test failure:
Failed tests:
ClusterClassificationDriverTest.testVectorClassificationWithOutlierRemovalMR:102->assertVectorsWithOutlierRemoval:188->checkClustersWithOutlierRemoval:238->Assert.assertTrue:41->Assert.fail:88
not expecting cluster:0:{0:1.0,1:1.0}
Here's the stack trace when I run that test:
java.lang.AssertionError: not expecting cluster:0:{0:1.0,1:1.0}
