The repository contains code for Stream Programming course project regarding streaming twitter data using Apache Spark. The project requires access to your twitter app, to get the following Key and Access Tokens:

• Consumer Key (API Key)
• Consumer Secret (API Secret)
• Access Token
• Access Token Secret

Apart from that, we need to add twitter4j library dependency to build.sbt file.

In a resources dir you can find twitter.txt file where you can pass your twitter credentials in the following format: (this is only example, you'll need to generate your own keys)

accessTokenSecret gkQa5Wcvpzz0RVMz3jtIsY9polDYXyj20JoCykZeUU66f

For now, in the project there is one scala class -- KafkaDataCollector where you can find defined Kafka properties and access/set them by get/set methods. This class generates KafkaProducer to collect tweets from stream in real time.

The Object KafkaStreaming is the place where KafkaDataCollector is instantiated and ran.

In a SparkKafkaLoader Spark and Kafka are integrated and using Spark we can read stream data into DataFrame.

The code regarding twitter data sentiment / nlp analysis is a work in progress :)
