> I noticed that there is an unhandled case in the transform method of VectorAssembler if one of the input columns doesn't have one of the supported type DoubleType, NumericType, BooleanType or VectorUDT. 
> So, if you try to transform a column of StringType you get a cryptic "scala.MatchError: StringType".
> Will submit a PR shortly
