KafkaStreamingWordCountApp

object KafkaStreamingWordCountApp extends App with Logging with Assertions

Simple Kafka Spark Streaming demo which 1. Starts an embedded ZooKeeper server 2. Starts an embedded Kafka server 3. Creates a new topic in the Kafka broker 4. Generates messages and publishes to the Kafka broker 5. Creates a Spark Streaming Kafka input stream which pulls messages from a Kafka Broker, runs basic Spark computations on the streaming data, and writes results to Cassandra 6. Asserts expectations are met 7. Shuts down Spark, Kafka and ZooKeeper
