Spark 1.5.2 : change datatype in programaticallly generated schema

[Divya Gehlot]

Hi,

I am generating schema programatically  as show below
val schemaFile = sc.textFile("/TestDivya/Spark/cars.csv")
 val schemaString = schemaFile.first()
val schema =
      StructType(Array(
        schemaString.split(" ").map(fieldName => StructField(fieldName,
StringType(), true))))

I want to change the datatype of year column to int  and for many other
columns as my schemaString is huge with more than 100+ columns
any suggestions?


Thanks,
Divya
