The Hortonworks Blog

It’s been a huge couple of weeks for us at Hortonworks HQ. We’ve talked about the GA of Hadoop 2, the subsequent release of Hortonworks Data Platform 2.0, and a little of the future with Apache Storm. We’ve been staggered by the support, goodwill and enthusiasm we’ve seen from you all.

We hope you’re as excited about Hadoop as we are, and we wanted to say thanks to our amazing team, amazing customers, amazing partners and the most amazing community for doing Hadoop with us – THANK YOU.…

We’re continuing our series of quick interviews with Apache Hadoop project committers at Hortonworks.

This week Mahadev Konar discusses Apache Ambari, the open source Apache project to simplify management of a Hadoop cluster.

Mahadev was on the team at Yahoo! in 2006 that started developing what became Apache Hadoop. Since then, he has also held leadership positions in the Apache Zookeeper and Apache Ambari projects. He is an architect and project management committee member for Apache Ambari, Apache ZooKeeper and Apache Hadoop.…

What a difference a year makes! Last Fall Ambari was a nascent Apache project that had recently shipped an inaugural release in the community. Fast forward a bit, at the beginning of this year Ambari shipped what has become the foundation for rapid innovation. Now Ambari has become a key member of the Apache Hadoop project ecosystem and a trusted operational platform for many companies.

Let’s take a brief look at the community’s amazing accomplishments over the past year, and then take some time to look forward.…

The Hadoop Distributed File System is the reliable and scalable data core of the Hortonworks Data Platform. In HDP 2.0, YARN + HDFS combine to form the distributed operating system for your Data Platform, providing resource management and scalable data storage to the next generation of analytical applications.

Over the past six months, HDFS has introduced a slew of major features to HDFS covering Enterprise Multi-tenancy, Business Continuity Processing and Enterprise Integration:

  • Enabled automated failover with a hot standby and full stack resiliency for the NameNode master service
  • Added enterprise standard NFS read/write access to HDFS
  • Enabled point in time recovery with Snapshots in HDFS
  • Wire Encryption for HDFS Data Transfer Protocol

Looking forward, there are evolving patterns in Data Center infrastructure and Analytical applications that are driving the evolution of HDFS.…

This post is the sixth in our series on the motivations, architecture and performance gains of Apache Tez for data processing in Hadoop. The series has the following posts:

Motivation

Tez follows the traditional Hadoop model of dividing a job into individual tasks, all of which are run as processes via YARN, on the users’ behalf – for isolation, among other reasons.…

Today, with overwhelming partner support, we announced GA of Hortonworks Data Platform 2.0 (HDP 2.0).  With 17 certified partners and many more in the works, organizations can confidently get started taking advantage of Hadoop 2.0 its YARN based architecture knowing that the technologies they rely on, run on HDP 2.0.

With a YARN-based architecture that serves as the operating system for Hadoop, HDP 2.0 takes Hadoop beyond single-use, batch processing to a fully functional,  multi-use platform that enables batch, interactive, online and stream processing.…

Typical delivery of enterprise software involves a very controlled date with a secret roadmap designed to wow prospects, customers, press and analysts…or at least that is the way it usually works.  Open source, however, changes this equation.

As described here, the vision for extending Hadoop beyond its batch-only roots in support of interactive and real-time workloads was set by Arun Murthy back in 2008. The initiation of YARN, the key technology for enabling this vision, started in earnest in 2011, was declared GA by the community in the recent Apache Hadoop 2.2 release, and is now delivered for mainstream enterprises and the broader commercial ecosystem with the release of Hortonworks Data Platform 2.0.…

The last couple of weeks have been a period of intense activity around the Apache projects that comprise the Hadoop ecosystem. While most of the headlines were accorded to Apache Hadoop 2 going GA, it would be remiss not to pay attention to the great progress being made in the Apache projects that complement Hadoop.

We have blogged about these over the course of the past week and the list below provides a quick summary of the phenomenal work contributed in the open by the folks driving these diverse and vital communities.…

Today we are proud to announce the general availability of Apache Pig 0.12!

If you are a Pig user and you’ve been yearning to use additional languages, for more data validation tools, for more expressions, operators and data types, then read on. Version 0.12 includes all of those additions, and now Pig runs on Windows without Cygwin.

This was a great team effort over the past six months with over 30 engineers from Twitter, Yahoo, LinkedIn, Netflix, Microsoft, IBM, Salesforce, Mortardata, Cloudera and several others (including Hortonworks of course).…

Today we are proud to announce the delivery of Apache Ambari 1.4.1. Ambari 1.4.1 combines many months of work in the community advancing the Ambari codebase. Over 760 JIRAs have been resolved since the Ambari 1.2.5 release. We would like to thank the nearly 40 engineers who contributed to help make this release possible.

Hello Hadoop 2, Meet Apache Ambari
The most important addition to Ambari 1.4.1 is support for installing, managing and monitoring a cluster based on the Hadoop 2 stack.…

The Hortonworks HBase team is excited to see HBase 96 released.  It represents a broad community effort and massive amount of work that has been building for more than a year.

HBase 96 closes out over 2000 issues (2134 Jira tickets to be exact) and it represented the collective work from a VERY active community. Kudos to everyone involved! As the authors in a recent Apache blog alluded to, the HBase community is very healthy and includes developers from many companies including Hortonworks, Yahoo!, Cloudera, Salesforce, eBay, Intel, and Facebook, just to name just a few.…

This post is authored by Omkar Vinit Joshi with Vinod Kumar Vavilapalli and is the 8th post in the multi-part blog series on Apache Hadoop YARN – a general-purpose, distributed, application management framework that supersedes the classic Apache Hadoop MapReduce framework for processing data in Hadoop clusters. Other posts in this series: 

Introduction

In YARN, applications perform their work by running containers, which today map to processes on the underlying operating system.…

Today we announced the Analytics Advantage with Hadoop offering from SAS, Teradata and Hortonworks. The new offering leverages the capabilities for in-database data preparation, analytic model building and deployment and combines Teradata’s Appliance for SAS® High-Performance Analytics offering with the Teradata Appliance for Hadoop built on Hortonworks Data Platform. Using Teradata’s Unified Data Architecture (UDA), this high-speed integrated offering allows customers to discover, build and deploy analytic models across data stored in Teradata and Hadoop, promoting businesses’ ability to act upon analytic insights from any type of data across a seamless environment and faster than ever before.…

You did it! Last Sunday we challenged you to “Learn Hadoop in 7 days”. We hope that you have risen to the test and kept up with the tutorials we’ve posted each day through Twitter and Facebook. These tutorials should have helped you delve into:

By now, you should feel comfortable with Hadoop clickstream analysis, Hortonworks ODBC driver configuration, and many other important components of Hadoop.…

This post’s Principal Author: Ming Ma, Software Development Manager, eBay.  With contribution from Mayank Bansal (eBay), Devaraj Das (Hortonworks), Nicolas Liochon (Scaled Risk), Michael Weng (eBay), Ted Yu (Hortonworks), John Zhao (eBay)

eBay runs Apache Hadoop at extreme scale, with tens of petabytes of data. Hadoop was created for computing challenges like ours, and eBay runs some of the largest Hadoop clusters in existence.

Our business uses Apache HBase to deliver value to our customers in real-time and we are sensitive to any failures because prolonged recovery times significantly degrade site performance and result in material loss of revenue. …
