Zeppelin tutorial load data into table fails with error about toDF()

Run the Zeppelin tutorial against HDP Spark.

The Load Data Into Table step fails with

import sys.process._
sqlContext: org.apache.spark.sql.SQLContext = org.apache.spark.sql.SQLContext@6d7637b5
bankText: org.apache.spark.rdd.RDD[String] = bank-full.csv MappedRDD[1] at textFile at <console>:24
defined class Bank
<console>:34: error: value toDF is not a member of org.apache.spark.rdd.RDD[Bank]
possible cause: maybe a semicolon is missing before `value toDF'?
       ).toDF()

Reason:
The toDF() method is available in Spark 1.3 only and not the version of Spark supported by HDP 2.2 (Spark 1.2.1). Remove it and the example should run successfully.
