### How should this be tested?
`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 map data
val myMapText = sc.parallelize(
IOUtils.toString(
new
URL("https://gist.githubusercontent.com/Madhuka/74cb9a6577c87aa7d2fd/raw/2f758d33d28ddc01c162293ad45dc16be2806a6b/data.csv";),
Charset.forName("utf8")).split("\n"))
case class Map(Country:String, Name:String, lat : Float, lan : Float,
Altitude : Float)
val myMap = myMapText.map(s=>s.split(",")).filter(s=>s(0)!="Country").map(
s=>Map(s(0),
s(1),
s(2).toFloat,
s(3).toFloat,
s(4).toFloat
)
)
// Below line works only in spark 1.3.0.
// For spark 1.1.x and spark 1.2.x,\n// use
myMap.registerTempTable(\"myMap\") instead.\n
myMap.toDF().registerTempTable("myMap")`
### Screenshots (if appropriate)
Can found in #152
### Questions:
* Does the licenses files need update?No
* Is there breaking changes for older versions?No
* Does this needs documentation? #152 contains documentation (I will add
new doc and sample in new PR)
