## Example Paragraph for Testing

```scala

import org.apache.commons.io.IOUtils

import java.net.URL

import java.nio.charset.Charset

// Zeppelin creates and injects sc (SparkContext) and sqlContext (HiveContext or SqlContext)

// So you don't need create them manually

// load bank data

val bankText = sc.parallelize(

    IOUtils.toString(

        new URL("https://s3.amazonaws.com/apache-zeppelin/tutorial/bank/bank.csv"),

        Charset.forName("utf8")).split("\n"))

case class Bank(age: Integer, job: String, marital: String, education: String, balance: Integer)

val bank = bankText.map(s => s.split(";")).filter(s => s(0) != "\"age\"").map(

    s => Bank(s(0).toInt, 

            s(1).replaceAll("\"", ""),

            s(2).replaceAll("\"", ""),

            s(3).replaceAll("\"", ""),

            s(5).replaceAll("\"", "").toInt

        )

).toDF()

bank.registerTempTable("bank")

```

```

%sql 

select age, job, marital, education, avg(balance) as average

from bank

group by age, job, marital, education

limit 100

```
