case class fails on remote spark

I am testing use of scala case class in a zeppelin instance provided by an Horontoworks Data Platform stack.

The bug is reproducible with following instructions:

 

Copy/paste in zeppelin instructions from https://zeppelin.apache.org/docs/0.5.5-incubating/tutorial/tutorial.html. (full screenshot attached)

In a first cell, instructions to create the RDD and then the temporary table.

 

After execution, I get "console>:37: error: value toDF is not a member of org.apache.spark.rdd.RDD[Bank] bank.toDF().registerTempTable("bank") 

 

Second cell is the first sql query in the tutorial.

 

Execution fails with:

java.lang.ArrayIndexOutOfBoundsException: 5

The exact basic tutorial code (i.e. access to amazone and building a local in memory rdd) seems to work in remote zeppelin (i.e. sql provides results) but I still get  "value toDF is not a member of org.apache.spark.rdd.RDD[Bank] ".

 

Testing the basic tutorial code in a local 0.8.0 zeppelin works without any issue.
