Continuuity Reactor 2.1: New Developer Experience and Windows Support

Sreevatsan Raman is the Head of Engineering at Cask where he is driving the company's engineering initiatives. Prior to Cask, Sree designed and implemented big data infrastructure at Klout and Yahoo!

Please note: Continuuity is now known as Cask, and Continuuity Reactor is now known as the Cask Data Application Platform (CDAP).

Last November at Strata + Hadoop World 2013, we came out of public beta and launched Continuuity Reactor 2.0. Our goal was to enable developers and businesses to deploy production Big Data applications on our platform. Since then, we’ve been maniacally focused on making our developer experience better for all Java developers, with or without Hadoop experience. Today, we’re happy to announce the next version of Continuuity Reactor: 2.1.

In Continuuity Reactor 2.1 release, we have the following new features:

New Developer Experience

We completely revamped our developer documentation and out-of-the-box experience to make it easier for Java developers–who may not be familiar with Hadoop or Big Data–to get started with Continuuity Reactor. We added real-world examples for you to get a quick and simple overview of our platform, a helpful guide to the Reactor user interface, and a streamlined SDK download so you can get started without missing a beat.

Windows Support

Some developers build Big Data applications on Windows machines. So, we added support for running single-node Reactor on 64-bit Windows (Windows XP and above).

Additional Features

The new release will add support for HBase 0.96, which has features like improved scalability, lower mean-time-to-recovery, and support for larger clusters (more than hundreds of nodes). We also fixed a number of bugs and made our platform more stable.

We are working hard to solve the problems faced by both new and experienced Big Data developers. Reactor unifies the capabilities you need, in an integrated developer experience, without the worries of distributed system architectures or scalability. You will hear more from us as we progress, and we would love to hear from you. Feel free to leave a comment or send us feedback at

Happy hacking!
