The Hortonworks Blog

A transformation is occurring in the data center.  Enterprises are turning to a modern data architecture in order to derive maximum value from both big and small data across their organization.  They are building new analytic apps that unlock opportunity and allow them to maintain or create competitive edge. Apache Hadoop is at the center of this architecture and integrates with the technologies that run your business to augment and extend this new value.…

Hortonworks Software Engineers Vinod Kumar Vavilapalli (Apache Hadoop YARN committer) and Jian He (Apache YARN Hadoop committer) discuss Apache Hadoop YARN’s Resource Manager resiliency upon restart in this blog.This is their third blog post in our series on motivations and architecture for improvements to the Apache Hadoop YARN’s Resource Manager (RM) resiliency. Others in the series are:

Introduction Phase II – Preserving work-in-progress of running applications

ResourceManager-restart is a critical feature that allows YARN applications to be able to continue functioning even when the ResourceManager (RM) crash-reboots due to various reasons.…

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.  …

“Data is to information society what fuel was to the industrial economy: the critical resource powering the innovations that people rely on,” write Victor Mayer-Schönberger and Kenneth Cukier, in Big Data. Today, big data fuels and engenders innovation of new products and services, according to Forrester.

Just as countries’ fuel repositories need protection and security because they can come under attack, so do companies’ big data repositories. “Companies, markets, and countries are increasingly under attack from cyber-criminals.…

It’s been a busy year for Apache Ambari. Keeping up with the rapid innovation in the open community certainly is exciting. We’ve already seen six releases this year to maintain a steady drumbeat of new features and usability guardrails. We have also seen some exciting announcements of new folks jumping into the Ambari community.

With all these releases and community activities, let’s take a break to talk about how the broader Hadoop community is affecting Ambari and how this is influencing what you will see from Ambari in the future.…

Apache Hadoop has come along a long way. From its early days as a platform to index the web, it has evolved to its current interactive, real-time, and batch processing capabilities spanning gigabytes to petabytes of content. A key stepping stone in this evolution has been Apache Hadoop YARN. YARN has enabled enterprises to onboard “fit for purpose” processing engines to its Hadoop Data Lake. This has opened the Data Lake to rapid and unbridled innovation by the ISV community and delivered differentiated insight to the enterprise.…

SequenceIQ provides an API and platform to build predictive applications and turn data into tangible assets. In this guest blog, SequenceIQ Co-founder and CTO Janos Matyas (@sequenceiq), explains why his team chose Apache Ambari for provisioning Hadoop clusters and how they contributed to the Ambari project.

At SequenceIQ, we frequently provision Hadoop clusters on different environments. For a long time, we searched for the right provisioning and management tool.…

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.…

Apache Hadoop clusters grow and change with use. Maybe you used Apache Ambari to build your initial cluster with a base set of Hadoop services targeting known use cases and now you want to add other services for new use cases. Or you may just need to expand the storage and processing capacity of the cluster.

Ambari can help in both scenarios. In this blog, we’ll cover a few different ways that Ambari can help you expand your cluster.…

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.…

There are many projects that have been contributed to the Apache Software Foundation (ASF) by both vendors and users alike that greatly expand Apache Hadoop’s capabilities as an enterprise data platform.

While Hadoop – with YARN at its architectural center – provides the foundational capabilities for managing and accessing data at scale, a broader blueprint for Enterprise Hadoop has emerged that specifies how this array of Apache projects fit across five distinct pillars to form a complete enterprise data platform: data access, data management, security, operations and governance.…

Today we are excited to announce a deepening of our strategic partnership with HP . This news builds on the reseller partnership that we established in 2013 enabling HP to resell the Hortonworks Data Platform. It also allows us to build on the HP AllianceOne ConvergedSystems Partner of the Year Award that we received at the recent HP Discover 2014 conference for our strategic partnership.

Given the rapid adoption of Enterprise Hadoop as a core component of a modern data architecture combined with the fact that HP is the world’s leading server vendor in terms of shipments AND revenues according to IDC – meaning a significant number of those Hadoop nodes are being deployed with HP technologies – it’s hardly surprising that we’ve been collaborating closely.…

Although the Hadoop Summit San Jose 2014 has come and gone, the invaluable content—keynotes, sessions, and tracks—is available here. We ’ve selected a few sessions for Hadoop developers, practitioners, and architects, curating them under Apache Hadoop YARN, the architectural center and the data operating system.

In most of the keynotes and tracks three themes resonated:

  • Enterprises are transitioning from traditional Hadoop to modern Hadoop 2.
  • YARN is an enabler, the central orchestrator that facilitates multiple workloads, runs multiple data engines, and supports multiple access patterns—batch, interactive, streaming, and real-time—in Apache Hadoop 2.
  • Last week, Apache Tez graduated to become a top level project within the Apache Software Foundation (ASF). This represents a major step forward for the project and is representative of its momentum that has been built by a broad community of developers from not only Hortonworks but Cloudera, Facebook, LinkedIn, Microsoft, NASA JPL, Twitter, and Yahoo as well.

    What is Apache Tez and why is it useful?

    Apache™ Tez is an extensible framework for building YARN based, high performance batch and interactive data processing applications in Hadoop that need to handle TB to PB scale datasets.…

    The Apache Pig community released Pig 0.13. earlier this month. Pig uses a simple scripting language to perform complex transformations on data stored in Apache Hadoop. The Pig community has been working diligently to prepare Pig to take advantage of the DAG processing capabilities in Apache Tez. We also improved usability and performance.

    This blog post summarizes the progress we’ve made.

    Support for Backends Other Than MapReduce

    We made the Pig 0.13 architecture more general to support multiple backends beyond just MapReduce, while maintaining backward compatibility.…
