> In KMeansSuite and BisectingKMeansSuite, there are some unused lines:
>  
> {code:java}
> model1.clusterCenters.forall(Vectors.norm(_, 2) == 1.0 {code}
>  
> For cosine distance, the norm of centering vector should be 1, so the norm 
> checking is meaningful;
> For euclidean distance, the norm checking is meaningless;
