We are excited to announce that Apache Kafka 0.8.1.1 is now available as a technical preview with Hortonworks Data Platform 2.1. Kafka was originally developed at LinkedIn and incubated as an Apache project in 2011. It graduated to a top-level Apache project in October of 2012.

Many organizations already use Kafka for their data pipelines, including Hortonworks customers like Spotify and Tagged.

What is Apache Kafka?

Apache Kafka is a fast, scalable, durable, and fault-tolerant publish-subscribe messaging system.…

YARN and Apache Storm: A Powerful Combination

YARN changed the game for all data access engines in Apache Hadoop. As part of Hadoop 2, YARN took the resource management capabilities that were in MapReduce and packaged them for use by new engines. Now Apache Storm is one of those data-processing engines that can run alongside many others, coordinated by YARN.

YARN’s architecture makes it much easier for users to build and run multiple applications in Hadoop, all sharing a common resource manager.…

HP and Hortonworks recently announced a strategic partnership that included a $50 million equity investment by HP. While the investment is important, there is an equally important joint commitment to help accelerate the adoption of Enterprise Apache Hadoop by deeply integrating the Hortonworks Data Platform (HDP) with the HP HAVEn big data platform.

Below are some thoughts on our joint work from the HP OMi Team…

The first area of joint engineering strategy between our companies will be to integrate Apache Ambari with HP Operations Manager i (OMi) which provides tools and APIs to provision, manage and monitor Hadoop clusters.  …

StackIQ, a Hortonworks technology partner, offers a comprehensive software suite that automates the deployment, provisioning, and management of Big Infrastructure. In this guest blog, Anoop Rajendra (@anoop_r), a Senior Software Developer at StackIQ, gives instructions for using StackIQ Cluster Manager to deploy Apache Ambari on a cluster running Hortonworks Data Platform (HDP).

Provisioning, managing and monitoring an Apache™ Hadoop cluster can be challenging. With this in mind, the engineers at Hortonworks introduced the Apache Ambari project into the Apache Software Foundation.…

Earlier this month, the Apache Ambari community released Apache Ambari 1.6.1, which includes multiple improvements for performance and usability. The momentum in and around the Ambari community is unstoppable. Today we saw the Pivotal team lean in to Ambari, and this is the sixth release of this critical component in 2014, proving again that open source is the fastest path to innovation.

Many thanks to the wealth of contribution from the broad Ambari community that resulted in 585 JIRA issues being resolved in this release.…

Apache Cassandra is an open source NoSQL distributed database management system designed to handle large amounts of data offering a scalable real time solution that allows users to create online applications that are “always-on, no matter what.” DataStax is the company behind Cassandra, and a new Technology Partner of Hortonworks.

Even more exciting are the numerous discussions we have had with current customers and prospects on how we can bring together a comprehensive and holistic security capabilities to HDP.  We now begin the journey to incubate our XA Secure functionality as a completely open source project governed by the Apache Software Foundation.…

Customers’ Hadoop Journey

We’ve all had two weeks to reflect on Hadoop Summit 2014. One of the biggest differences that stood out in this year’s Summit (as compared to Summit 2013) was the presence of large enterprise customers that are using Apache Hadoop as an important part of their modern data architectures.

Hadoop has gone beyond its original Yahoo use case—indexing the web via a nightly batch MapReduce process —and into the mainstream of daily data processing and analytics with real-time, online, interactive, and batch applications at many notable companies.…
