> I use the code to read file and get a dataframe. When the colum number is olny 20, the
inferSchema paragrama work well. But when the number is up to 400, it doesn't work, and I
have to tell it the schema manually. the code is :
>  val df = spark.read.schema(schema).options(Map("header"->"true","quote"->",","inferSchema"->"true")).csv("/Users/ss/Documents/traindata/traindataAllNumber.csv")
