We worked with our customer, Hotels.com, to help them develop libraries and utilities around Apache Hive, the Apache ORC format and Cascading. It’s great to see the results released for the community. In this guest blog, Adrian Woodhead, Big Data Engineering Team […]

As YARN drives Hadoop’s emergence as a business-critical data platform, the enterprise requires more stringent data security capabilities. The Apache Ranger delivers a comprehensive approach to security for a Hadoop cluster. It provides a platform for centralized security policy administration across the core enterprise security requirements of authorization, audit and data protection. On June 10th, […]

In his blog, Tim Hall wrote, “Enterprises are embracing Apache Hadoop to enable their modern data architectures and power new analytic applications. The freedom to choose the on-premises or cloud environments for Hadoop that best meets the business needs is a critical requirement.” One of the choices in deploying Hadoop in the cloud environment is with Microsoft Azure using […]

Mayank Bansal, of EBay, is a guest contributing author of this collaborative blog. This is the 4th post in a series that explores the theme of enabling diverse workloads in YARN. See the introductory post to understand the context around all the new features for diverse workloads as part of Apache Hadoop YARN in HDP. Background  In Hadoop YARN’s […]

Introduction Multihoming is the practice of connecting a host to more than a single network. This is frequently used to provide network-level fault tolerance – if hosts are able to communicate on more than one network, the failure of one network will not render the hosts inaccessible. There are other use cases for multi-homing as […]

The Apache community released Apache Pig 0.15.0 last week.

The components in a modern data architecture vary from one enterprise to the next and the mix changes over time. Many of our Hortonworks subscribers need support ensuring that their Hortonworks Data Platform (HDP) clusters are optimally configured. This means that they need proactive, intelligent cluster analysis. As businesses onboard new workloads to the platform, […]

Apache Hadoop has emerged as a critical data platform to deliver business insights hidden in big data. As a relatively new technology, system administrators hold Hadoop to higher security standards. There are several reasons for this scrutiny: External ecosystem that comprise of data repositories and operational systems that feed Hadoop deployments are highly dynamic and […]

Last week, the Apache Slider community released Apache Slider 0.80.0. Although there are many new features in Slider 0.80.0, few innovations are particularly notable: Containerized application onboarding Seamless zero-downtime application upgrade Adding co-processors to app packages without reinstallation Simplified application onboarding without any packaging requirement Below are some details about these important features.

Not a day passes without someone tweeting or re-tweeting a blog on the virtues of Apache Spark. At a Memorial Day BBQ, an old friend proclaimed: “Spark is the new rub, just as Java was two decades ago. It’s a developers’ delight.” Spark as a distributed data processing and computing platform offers much of what […]

Apache Spark provides a lot of valuable tools for data science. With our release of Apache Spark 1.3.1 Technical Preview, the powerful Data Frame API is available on HDP. Data scientists use data exploration and visualization to help frame the question and fine tune the learning. Apache Zeppelin helps with this. Based on the concept […]
