Initializing SparkContext
This recipe shows how to initialize the SparkContext object as a part of many Spark applications. SparkContext is an object which allows us to create the base RDDs. Every Spark application must contain this object to interact with Spark. It is also used to initialize StreamingContext, SQLContext and HiveContext.
Getting ready
To step through this recipe, you will need a running Spark Cluster in any one of the modes that is, local, standalone, YARN, or Mesos. For installing Spark on a standalone cluster, please refer to http://spark.apache.org/docs/latest/spark-standalone.html. Install Hadoop (optional), Scala, and Java.
