Summary
In this chapter, we have installed Spark on our machine for local development and set it up on our cluster, and so we are ready to run the applications that we write. While installing and maintaining a cluster is a good option, Spark is also available as a service option from Databricks. Databricks' Databricks Cloud for Spark, available at http://databricks.com/product, is a very convenient offering for anyone who does not want to deal with the set up/maintenance of the cluster. They have the concept of a big data pipeline from ETL to analytics. This looks truly interesting to explore!
In the next chapter, you will learn to use the Spark shell.
