Apache Falcon gets top-level status, filling gap in Hadoop ecosystem

theCUBE Live at Hadoop World 2014

Hadoop marked another milestone along its breakneck evolution on Monday when Falcon, one of the most promising technologies in the upstream ecosystem, exited incubation to become a top-level project of the Apache Software Foundation. The news comes just a few short months after the inauguration of Storm as a real-time option for Hadoop.

Like the stream processing engine, Falcon traces its roots to a fast-growing web company that had to come up with a homegrown answer to its rapidly evolving requirements for lack of other options. In the case of mobile advertising powerhouse appMobi Inc., the challenge was effectively serving billions of data requests from with wildly varying requirements.

Certain actions, such as identifying the best location for a promotion at a particular moment, require prioritizing speed above everything else. In contrast, tasks like generating a report on campaign effectiveness demand accuracy even if it means delaying delivery. Pinpointing and then meeting the specific needs of each workload in a timely fashion therefore becomes immensity difficult at large scale.

That’s where Falcon comes in. The project, which appMobi released to the community in July of 2013, provides a high-level framework for implementing automated controls to manage the flow of information. It allows engineers to specify exactly what action to carry out on a particular piece of information in a given scenario and uses Oozie, an earlier orchestration engine for Hadoop, to handle the execution.

That functionality is useful for a wide range of use cases extending far beyond merely matching a workload to the optimal processing paradigm. Falcon makes it possible to keep track of data as it moves through the different stages of analysis, a notoriously tricky task, and enforce limitations on how sensitive information such as medical records can be handled. It can also help coordinate tasks across multiple clusters.

The framework’s inauguration is a major step forward toward addressing the need for automation and policy enforcement capabilities in Hadoop, two of the most crucial sticking points among large enterprises. The boost comes not so much from the status upgrade itself but from Apache stamp of approval that provides validation in the eyes of the open-source community.
