We then need to create a Spark session as the gateway of our program:

val spark = SparkSession
        .builder
        .master("local[*]")
        .config("spark.sql.warehouse.dir", "tmp/")
        .appName("Fraud Detection")
        .getOrCreate()

Additionally, we need to import implicits for spark.sql and h2o:

implicit val sqlContext = spark.sqlContext
import sqlContext.implicits._
val h2oContext = H2OContext.getOrCreate(spark)
import h2oContext._
import h2oContext.implicits._
