I'm downstream stages the labels & features are generally expected to be
doubles, so its easier to use as a double.

Hi Spark,
StringIndex uses double instead of int for indexing
http://spark.apache.org/docs/latest/ml-features.html#stringindexer. What's
the rationale for using double to index? Would it be more appropriate to
use int to index (which is consistent with other place like Vector.sparse)
