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.…

Hadoop is a business-critical data platform at many of the world’s largest enterprises. These corporations require a layered security model focusing on four aspects of security: authentication, authorization, auditing, and data protection. Hortonworks continues to innovate in each of these areas, along with other members of the Apache open source community. In this blog, we will look at the authentication layer and how we can enforce strong authentication in HDP via Kerberos.…

Hadoop Summit Content Curation

Although the Hadoop Summit San Jose 2014 has come and gone, the invaluable content—keynotes, sessions, and tracks—is available here. I’ve selected a few sessions below for Hadoop system administrators and dev-ops, curating them under a general Hadoop operations theme.

Dev-ops engineers and system administrators know best that ease of operations and deployments can make or break a large Hadoop production cluster, which is why they care about all of the following:

  • how rapidly they can create or replicate a cluster;
  • how efficiently they can manage or monitor at scale;
  • how easily and programmatically they can extend or customize their operational scripts; and
  • how accurately they can foresee, forestall, or forecast resource starvation or capacity stipulation.

The Apache Storm community recently announced the release of Apache Storm 0.9.2, which includes improvements to Storm’s user interface and an overhaul of its netty-based transport.

We thank all who have contributed to Storm – whether through direct code contributions, documentation, bug reports, or helping other users on the mailing lists. Together, we resolved 112 JIRA issues.

Here are summaries of this version’s important fixes and improvements.

New Feature Highlights
Netty Transport Overhaul

Storm’s Netty-based transport has been overhauled to significantly improve performance through better utilization of thread, CPU, and network resources, particularly in cases where message sizes are small.…

Last Thursday we hosted the last of our seven Discover HDP 2.1 webinars, Using Apache Ambari to Manage Hadoop Clusters. Over 140 people attended and joined in the conversation.

The speakers gave an overview of Apache Ambari, discussed new features, and showed an end-to-end demo.

Thanks to our presenters Justin Sears (Hortonworks’ Product Marketing Manager), Jeff Sposetti (Hortonworks’ Senior Director of Product Management), and Mahadev Konar (Hortonworks’ Co-founder, Committer, and PMC Member for Apache Hadoop, Apache Ambari, and Apache Zookeeper) who presented the webinar.…

IBM InfoSphere Guardium has certified with HDP 2.1. The  Hortonworks Certified Technology Program simplifies big data planning by providing pre-built and validated integrations between leading enterprise technologies and HDP. 

Kathryn Zeidenstein, InfoSphere Guardium Evangelist, is our guest blogger and describes security, Hadoop, and the Guardium solution.

Those of us in the data security and privacy space tend to worry a lot. With each new breaking story on the latest data breach, and with the subsequent fallout, people higher and higher up the food chain are also worrying a lot.…

This week we hosted a webinar entitled HDP Advanced Security: Comprehensive Security for Enterprise Hadoop. Over 135 people attended, prompting an informative discourse and a series of questions.

The speakers outlined the HDP Advanced Security features and benefits in Hortonworks Data Platform and gave a demo. Thanks to our presenters Justin Sears (Hortonworks’ Product Marketing Manager), Balaji Ganesan (Hortonworks’ Senior Director, Enterprise Security Strategy), and Don Bosco Durai (Hortonworks’ Enterprise Security Architect).…

We recently hosted the sixth of our seven Discover HDP 2.1 webinars, entitled Apache Storm for Stream Data Processing in Hadoop. Over 200 people attended the webinar and joined in the conversation.

Thanks to our presenters Justin Sears (Hortonworks’ Product Marketing Manager), Himanshu Bari (Hortonworks’ Senior Product Manager for Storm), and Taylor Goetz (Hortonworks’ Software Engineer and Apache Storm Committer) who presented the webinar. The speakers covered:

  • Why use Apache Storm?

Apache YARN Ready Program

With the release of Apache Hadoop YARN in October of last year, organizations are moving from single-application Hadoop clusters to a versatile, integrated Hadoop 2 data platform hosting multiple applications — eliminating silos, maximizing resources and bringing true multi-workload capabilities to Hadoop.

Customers are telling us loud and clear: they want solutions that run on YARN because it enables them to run multiple workloads on the same common data pool.…

We’re finally catching our breath after a phenomenal Hadoop Summit event last week in San Jose.  Thank you to everyone that came to participate in the celebration of Hadoop advances and adoption—from many of the organizations that shared their Hadoop journey with us that fundamentally transformed their businesses, to those just getting started, to the huge ecosystem of vendors. It is amazing to be part of such a broad and deep community that is contributing to making the market for everyone.…
