Zeppelin + Scala: Consuming a HTTP endpoint

Summary

In our last post, we discussed on how could we execute Spark jobs in Zeppelin and then create nice SQL queries and graphs using the embedded SQLContext (provided along with the usual Spark context).

Today, we will see a way to populate your Spark RDDs/Data-Frames with data retrieved from a HTTP endpoint/REST service. We will focus on the parsing of the resulting JSON response. Additionally, we will also learn how to import additional libraries to Zeppelin.
