> Kmeans for synthetic control example(using default parameter), there are 12 clusters during iterators, but the goal is 6 clusters.
> why 12 not 6?
> before the first iteration, the hdfs dir "output/clusters-0/" will have 8 files: "_policy","part-00000" to "part-00005","part-randomSeed"."part-00000" to "part-00005" are 6 initial-clusters, and "part-randomSeed" is composed by this 6 initial-clusters. So in CIMapper.java's func "setup()" , the "classifier.readFromSeqFiles(conf, new Path(priorClustersPath));" will read 12 clusters not 6 clusters.
