Prerequisite knowledge

Attendees should have a basic understanding of the Hadoop ecosystem.

Materials or downloads needed in advance

You'll need a laptop if you'd like to follow along. Code for the demo and associated instructions are available here. Slides (subject to change) are available here.


Implementing a scalable, low-latency architecture requires understanding a broad range of frameworks, such as Kafka, HBase, HDFS, Flume, Spark, Spark Streaming, and Impala, among many others. The good news is that there’s an abundance of materials—books, websites, conferences, etc.—for gaining a deep understanding of these related projects. The bad news is there’s still a scarcity of information on how to integrate these components to implement complete solutions.

Jonathan Seidman, Mark Grover, Gwen Shapira, and Ted Malaska walk attendees through an end-to-end case study of building a fraud detection system. Throughout, Jonathan, Mark, Gwen, and Ted cover best practices and considerations for architecting real-time applications on Hadoop and explain how to create a fraud detection application using those best practices through a live demo of the full project on Cloudera’a Quickstart VM. The code for the demo will be available on GitHub so the audience can follow along. However, the tutorial is not “hands-on,” meaning that Jonathan, Mark, Gwen, and Ted will not attempt to walk you through building the application on your own Hadoop installation. As a result, this tutorial will be most valuable for developers, architects, or project leads who are already knowledgeable about Hadoop or similar distributed data processing systems and are now looking for more insight into how it can be leveraged to implement real-world applications.

Topics include:

  • Modeling data in Kafka, HBase, and Hadoop and selecting optimal formats for storing data
  • Integrating multiple data-collection, processing, and storage systems
  • Collecting and analyzing event-based data, such as logs and machine-generated data, and storing that data in Hadoop
  • Querying and reporting on data
