import hdfs://192.168.1.176/datasets/bestbuy_test.csv (import2) parse2, summary2 was fine. but then if I did summary1, (fvec to va?) it complained about NaN on the min in one of the NA'ed colls. Added protection to Summary1 for NaN in mins. same thing seems okay now. Maybe fvec parsing causes NaNs in places that va parsing didn't so that we might have NaNs in basicStats when we fvec to va, that we don't have if we import/parse in va only.  Curious why summary1 didn't hit NaN min problems before. does va parse protect somehow?
