The rapid adoption of Apache Hadoop and increasing capabilities of its ecosystem have made it a compelling platform for building applications. Hadoops architecture has allowed it to go beyond processing application-generated data to becoming a central component of products themselves, enabling a new generation of analytics-driven applications. In this presentation, Eli will give an overview of both how to build new applications with Hadoop, as well as how to integrate Hadoop with your existing applications. Eli will give an update on the state of Hadoop ecosystem for developers, covering the diverse set of frameworks and APIs useful for building different types of applications using Hadoop. Finally, Eli will cover issues like data management in the context of Hadoop-based applications.
