What would be the case like in CSV? I don't think anybody want to conbine
"user" and "User" column when "caseSensitiveAnalysis" is false.
`scala> val jsonDF = sqlContext.read.option("header",
"true").csv("file.csv")
jsonDF: org.apache.spark.sql.DataFrame = [user: string, User: string ... 1
more field]
scala> jsonDF.show
+-------+-------+-----+
| user| User| hits|
+-------+-------+-----+
| om| scala| 120|
| daniel| spark| 80|
|3754978| spark| 1|
+-------+-------+-----+`
