Today, the Forrester WaveTM: Big Data Hadoop Solutions, Q1 2014 was published by Forrester Research and while not surprised, we are delighted that this leading analyst firm recognized us as a clear leader in the Hadoop market. We could not be prouder of our unwavering strategy and hard work that is propelling us to the forefront of this burgeoning Hadoop market.

Download and review the report here.

Forrester evaluated nine vendors across a range of criterion from strategy to product and market presence and we scored a very balanced report across all categories and are way “up and to the right”.…

HBase is a distributed database built around the core concepts of an ordered write log and a log-structured merge tree. As with any database, optimized I/O is a critical concern to HBase. When possible, the priority is to not perform any I/O at all. This means that memory utilization and caching structures are of utmost importance. To this end, HBase maintains two cache structures: the “memory store” and the “block cache”.…

With over 230 JIRA tickets resolved, the Apache HBase community released 0.98.0 yesterday which is the next major version after 0.96.x series.

HBase 0.98.0 comes with an exciting set of new features with keeping the same stability improvements and features on top of 0.96. Additional to usual bug fixes, some of the major improvements include:

  • Reverse Scans (HBASE-4811): for use cases where both forward and reverse iteration is required, HBase now allows to perform scans in reverse mode.

The deployment of Big Data architectures has become more prevalent as organizations realize the power of what Big Data can bring to their businesses and to their profitability. …

Hadoop can be a great complement to existing data warehouse platforms, such as Teradata, as it naturally helps to address two key storage challenges:

The purpose of this article is to detail some of the key integration points and to show how data can be easily exchanged for enrichment between the two platforms.

As a data integrator who is familiar with RDBMS systems and is new to the Hadoop platform, I was looking for a simple way (i.e.…

With the growing number of large-scale enterprise deployments of big data, certain limitations have become more apparent bringing to light some weaknesses in this first phase of analytics infrastructures.  Hadoop, clearly a very valuable tool for the collection of unstructured data, poses some challenges that need to be overcome for wide spread successful enterprise adoption.

In our upcoming webinar on Tuesday Feb 19 at 10 am PT, we will address these issues and highlight how to solve them using Hortonworks Data Platform and our partner Actian.…

We are excited to announce an expansion of our relationship with open source leader Red Hat to a deeper more strategic alliance. The main goal is to help organizations adopt enterprise Apache Hadoop more quickly. This is a natural progression of our relationship with Red Hat because we are so closely aligned around a strategy of innovating in the open and applying enterprise rigor to open source software thereby de-risking it for the enterprise.…

In this post, we will explore how to quickly and easily spin up our own VM with Vagrant and Apache Ambari. Vagrant is very popular with developers as it lets one mirror the production environment in a VM while staying with all the IDEs and tools in the comfort of the host OS.

If you’re just looking to get started with Hadoop in a VM, then you can simply download the Hortonworks Sandbox.…

This guest post from Steve Ratay, Viewpoint Architect, Teradata Corporation

Teradata’s Unified Data Architecture is a powerful combination of the Teradata Enterprise Data Warehouse, the Aster Discovery Platform, Apache Hadoop (via the Hortonworks Data Platform) and Teradata Enterprise Management tools in a single architecture. 

If you are Teradata user managing an Enterprise Data Warehouse or Data Discovery platform, chances are that you are using Teradata Viewpoint, a monitoring and management platform for Teradata Systems. …

I recently sat down with Mahadev Konar and Jeff Sposetti to discuss Apache Ambari v1.4.1. Ambari 1.4.1 is a single framework to provision, manage and monitor clusters based on the Hadoop 2 stack, with YARN and NameNode HA on HDFS.

Mahadev is one of the original architects of Apache Hadoop, a co-founder of Hortonworks, and a committer on Apache Ambari and Apache ZooKeeper. Jeff is the Hortonworks product manager focused on Apache Ambari and Apache Falcon.…

In this post, we’ll walk through the process of deploying an Apache Hadoop 2 cluster on the EC2 cloud service offered by Amazon Web Services (AWS), using Hortonworks Data Platform.

Both EC2 and HDP offer many knobs and buttons to cater to your specific, performance, security, cost, data size, data protection and other requirements. I will not discuss most of these options in this blog as the goal is to walk through one particular path of deployment to get started.…

Apache Accumulo is gaining momentum in markets such as government, financial services and health care for its enhanced security and performance. Hortonworks has a long history with this technology and has multiple committers to the Accumulo project on staff – at least one of whom literally helped to write the book on Accumulo. This has enabled Hortonworks to provide enterprise support for Accumulo within the Hortonworks Data Platform for some time now.…

On Feb 8th and 9th, Hortonworks, Microsoft and Elastacloud will be hosting a hackathon at the Microsoft Campus in Mountain View, CA. Whether you’re a newbie or ninja, developer or scientist, we’d love to see you there. Register here.

The focus of the hackathon will be city datasets. For instance, we’ll be drawing on datasets from San Francisco that will measure things like:

  • Pedestrian safety: where accidents occur, how they occur and who has caused them.

I recently sat down with Himanshu Bari to discuss how Apache Ambari will serve as the single point of management for Hadoop 2 clusters integrated with Apache Storm and its real-time, streaming event processing.

Himanshu discusses Apache Storm’s five key benefits and how those will add to the power and stability of a Hadoop 2 stack, providing analysis of huge data flows from the second data is created and then for decades of historical analysis of that data stored in HDFS.…
