Sean Owen commented on SPARK-3284:
----------------------------------

>     val sc = new SparkContext(sparkConf)
>     val sqlContext = new org.apache.spark.sql.SQLContext(sc)
>     // createSchemaRDD is used to implicitly convert an RDD to a SchemaRDD.
>     import sqlContext.createSchemaRDD
>     val people = sc.textFile("C:/Users/pravesh.jain/Desktop/people/people.txt").map(_.split(",")).map(p
=> Person(p(0), p(1).trim.toInt))
>     people.saveAsParquetFile("C:/Users/pravesh.jain/Desktop/people/people.parquet")
>     val parquetFile = sqlContext.parquetFile("C:/Users/pravesh.jain/Desktop/people/people.parquet")

>     Exception in thread "main" java.lang.NullPointerException at org.apache.spark.parquet$.main(parquet.scala:16)
