Hello,

I am in the phase of learning Spark as part of it trying examples. I am using the following
lines of code as below for my file named df.scala:

import org.apache.spark.sql.SparkSession
val spark = SparkSession.builder().getOrCreate()
val df = spark.read.csv("CitiGroup2006_2008")
df.Head(5)

In my Scala Terminal:

scala> :load df.scala

Loading df.scala...
import org.apache.spark.sql.SparkSession
spark: org.apache.spark.sql.SparkSession = org.apache.spark.sql.SparkSession@4756e5cc
