I teach for Hortonworks and in class just this week I was asked to provide an example of using the R statistics language with Hadoop and Hive. The good news was that it can easily be done. The even better news is that it is actually possible to use a variety of tools: Python, Ruby, shell scripts and R to perform distributed fault tolerant processing of your data on a Hadoop cluster.…

Using Hadoop as an enterprise data platform means great integration with other technologies in the data center.
To that end, the Hortonworks Sandbox Partner Gallery showcases how our partners’ solutions integrate with Hadoop and provide you with easy access to learn how to use those solutions with the Hortonworks Data Platform via the Sandbox.
Don’t have the Sandbox? Get your free download of this single node Hadoop environment that’s delivered as a Virtual Machine that you can run on your laptop.…
When I first started to understand what YARN is, I wanted to build an application to understand its core. There was already a great example YARN application called Distributed Shell that I could use as the shell (pun intended) for my experiment. Now I just needed an existing application that could provide massive reuse value by other applications. I looked around and I decided on MemcacheD.
This brief guide shows how to get MemcacheD up and running on YARN – MOYA if you will…Prerequisites
You’re going to need a few things to get the sample application operational.…
As we have known for some time, Hortonworks customers are already building a modern data architecture with Hadoop as the technology of choice for handling the data they have streaming in from all directions. They care that it matches their needs, integrates with their existing infrastructure and solves real problems with flexibility.…
We’re delighted to announce that our Hadoop 2.0 Courseware is available now!
According to a 2013 Education Services Bench Mark Study conducted by The Technology Services Industry Association, “the lag time between product and Instructor Lead Content release is 68 business days, or more than three months” but not at Hortonworks! All of our Developer Courses and Certifications are now based on Apache Hadoop 2.0 and available at the same time as the Hortonworks Data Platform 2.0.…
One of the great things about working in open source development is working with other experts round the work on big projects – and then having the results of that work in the hands of users within a short period of time.
This is why I’m really excited about the Rackspace announcement of their HDP-based Big Data offerings, both “on-prem” and in cloud. Not just because its partners of us offering a service based on Hadoop, but because it shows how Hadoop integration with OpenStack has reached a point where it’s ready for production use.…
The Apache Knox community announced the release of the Apache Knox Gateway (Incubator) 0.3.0. We, at Hortonworks, are excited about this announcement.
The Apache Knox Gateway is a REST API Gateway for Hadoop with a focus on enterprise security integration. It provides a simple and extensible model for securing access to Hadoop core and ecosystem REST APIs.
Apache Knox provides pluggable authentication to LDAP and trusted identity providers as well as service level authorization and more. …
With the attention of the Hadoop community on Strata/Hadoop World in New York this week, it’s seems an appropriate time to give everyone an early update on continued community development of Apache Hive. This progress well and truly cements Hive as the standard open-source SQL solution for the Apache Hadoop ecosystem for not just extremely large-scale, batch queries but also for low-latency, human-interactive queries.
You can catch me at our session ‘Apache Hive & Stinger: Petabyte Scale SQL, IN Hadoop’ along with Owen and Alan where we’ll be happy to dive into more of the details.…
- Based on HDP 2.0
- Easy enablement of Ambari and Hbase
- Updated tutorial navigation
This version of the Sandbox provides you a complete HDP 2.0 environment. Your own personal single-node Hadoop cluster where you can explore the new features and enhancements of HDP 2.0, including YARN, the improvements to Hive that were delivered by the Stinger initiative, along with the updates to Hbase, Pig, and Ambari.In fact, our Sandbox has all of the most current releases of the various Apache Projects — like Hive 12, HBase 96, and Hadoop 2.2.…
You’re a Java developer, you use Spring and you’re just itching to get your arms around some big data. Well, now you can do that even easier than before as we announced this morning that Spring is now certified for Hortonworks Data Platform.
To celebrate this development, we have a community tutorial for Sandbox (1.3 currently) that shows you how to use Spring XD to collect data streamed from Twitter, load into HDFS and then run simple sentiment analysis with Apache Hive.…
Today we announced the expansion of our strategic relationship with HP enabling HP to resell Hortonworks Data Platform (HDP). As data volumes grow and new data sources emerge it is important for enterprises have access to production ready enterprise Apache Hadoop to meet their big data needs.
Today our partner Rackspace announced their Big Data solution for dedicated and cloud environments, powered by Hortonworks Data Platform. This collaboration between Hortonworks and Rackspace provides customers a flexible choice of deployment offerings of Apache Hadoop from one of the most trusted vendors in the cloud computing market.
Enterprise adoption of Apache Hadoop
This expanded collaboration is a strong indicator of the ecosystem rallying around Hortonworks Data Platform and our goal at Hortonworks of making Apache Hadoop a core component of the modern data architecture, whether on premise, in a VM, as an appliance, or in the cloud.…
Now that Hortonworks Data Platform 2.0 is GA, you may be looking to migrate your Hadoop stack from another version to take advantage of Hadoop 2’s YARN-based architecture. Fortunately, our Professional Services & Support teams are getting a lot of practice at migration from other distributions as more and more customers turn to 100% enterprise-hardened Apache Hadoop for their big data platform.
While any specific migration may have a few gotchas from a vendor lock-in, or business integration perspective, this high-level process overview is battle tested on large-scale production clusters and we hope it helps you plan for your own migration.…
