Answer 1

Here is a Simple Example How you can generate timeuuid :

import org.apache.spark.sql.SQLContext    
val sqlcontext = new SQLContext(sc)

import sqlcontext.implicits._

//Import UUIDs that contains the method timeBased()
import com.datastax.driver.core.utils.UUIDs

//user define function timeUUID  which will retrun time based uuid      
val timeUUID = udf(() => UUIDs.timeBased().toString)

//sample query to test, you can change it to yours
val df_newrecords = sqlcontext.sql("SELECT 1 as data UNION SELECT 2 as data").withColumn("time_uuid", timeUUID())

//print all the rows
df_newrecords.collect().foreach(println)

Output :

[1,9a81b3c0-170b-11e7-98bf-9bb55f3128dd]
[2,9a831350-170b-11e7-98bf-9bb55f3128dd]
