Joseph K. Bradley commented on SPARK-12363:
-------------------------------------------

Thanks for identifying this.  What do the predictions look like?  Does it 
improve if you increase the number of iterations KMeans runs for when called 
from PIC?

It seems like an intuitively reasonable test, but I could see it failing for 
bad initial cluster centers or if KMeans needs to run for more iterations.

> PowerIterationClustering test case failed if we deprecated KMeans.setRuns
