A Cosmopolitan Metropolis

Brussels, Belgium, conjures images of a cosmopolitan metropolis, where geopolitical summits are held, where world economic forums are debated, where global European institutions are headquartered, and where citizens and diplomats fluently converse in more than three languages—English, French, Dutch or German, along with other non-official local flavors.

To this colorful collage, add the image of a Hadoop Summit Europe 2015 for big data developers, practitioners, industry experts, and entrepreneurs, who make a difference in the digital world, who fluently code in multiple programming languages—Java, Python, Scala, C++, Pig, SQL, or R—and innovate and incubate Apache projects.…

In part 1, Kenneth Peeples, JBoss technology evangelist and principal marketing manager for Data Virtualization and Fuse Service Works at Red Hat, gave us an overview of the Red Hat and Hortonworks webinar series and offered insights into JBoss Data Virtualization and HDP. He started with an overview of data virtualization with the Hortonworks Data Platform and went over the first use case, Sentiment and Sales Analysis. Today, he describes the three other use cases.…

Last week Hortonworks presented the first of 8 Discover HDP 2.2 webinars: Comprehensive Hadoop Security with Apache Ranger and Apache Knox. Vinay Shukla and Balaji Ganesan hosted this first webinar in the series.

Balaji discussed how to use Apache Ranger (for centralized security administration, to set up authorization policies, and to monitor user activity with auditing. He also covered Ranger innovations now included in HDP 2.2:

  • Support for Apache Knox and Apache Storm, for centralized authorization and auditing
  • Deeper integration of Ranger with the Apache Hadoop stack with support for local grant/revoke in HDFS and HBase
  • Ranger’s enterprise readiness, with the introduction of REST APIs for policy management, and scalable storage of audit in HDFS

Vinay presented Apache Knox and API security for Apache Hadoop.…

Joe Travaglini, director of product marketing at Sqrrl and Ely Kahn, vice president of business development at Sqrrl, are our guest bloggers. They explain Sqrrl’s integration with Hortonworks Data Platform (HDP).

There Is No Secure Perimeter

With the dawn of phenomena such as Cloud Computing and Bring Your Own Device (BYOD), it is no longer the case that there is a well-defined perimeter to secure and defend. Data is able to flow inside, outside, and across your network boundaries with limited interference from traditional controls.…

Enterprise Apache Hadoop provides the fundamental data services required to deploy into existing architectures. These include security, governance and operations services, in addition to Hadoop’s original core capabilities for data management and data access. This post focuses on recent work completed in the open source community to enhance the Hadoop security component, with encryption and SSL certificates.

Last year I wrote a blog summarizing wire encryption options in Hortonworks Data Platform (HDP).…

Introduction

Hortonworks University announces a new operationally focused course for Apache Hadoop administrators. This two-day training course is designed for Hadoop administrators who are familiar with administering other Hadoop distributions and are migrating to the Hortonworks Data Platform (HDP). Through a combination of lecture and hands-on exercises you will learn how to install, configure, maintain and scale an HDP cluster

Target Audience

This course is designed for experienced Hadoop administrators and operators who will be responsible for installing, configuring and supporting the Hortonworks Data Platform.…

Hortonworks Data Platform Version 2.2 represents yet another major step forward for Hadoop as the foundation of a Modern Data Architecture. This release incorporates the last six months of innovation and includes more than a hundred new features and closes thousands of issues across Apache Hadoop and its related projects.

Our approach at Hortonworks is to enable a Modern Data Architecture with YARN as the architectural center, supported by key capabilities required of an enterprise data platform — spanning Governance, Security and Operations.…

Apache Hadoop has taken a mission critical role in the Modern Data Architecture (MDA) with the advent of Apache Hadoop YARN. YARN has enabled enterprises to store and process data across many execution engines at a scale that has not been possible earlier. This in turn has made security a crucial component of enterprise Hadoop. At Hortonworks we have broken the problem of enterprise security into four key areas of focus: authentication, authorization, auditing and data protection.…

As more companies turn to Hadoop as a crucial data platform, we are seeing security considerations continuing to play a much bigger role. Dataguise DgSecure works in concert with the Hortonworks Data Platform (HDP) to bring enterprise grade security and insight to Hadoop deployments. Data governance professionals can employ critical security features such as centrally managed authorization and audit, as well as sensitive data discovery, data centric protection and reporting to their Hadoop deployments.…

Thanks to all who joined us on our Hortonworks/Voltage webinar, “Securing Hadoop: What are Your Options?” For those who couldn’t attend, we’re sorry we missed you. We’ve included a link to the webinar recording below, and please listen in!

On the webinar, Hortonworks’ Vinod Nair presented the recently-announced Apache Argus incubator: a central policy administration framework across security requirements for authentication, authorization, auditing and data protection. Sudeep Venkatesh, of Voltage Security, defined data-centric protection technologies that easily integrate with Hive, Sqoop, MapReduce and other Hadoop interfaces.…

Haohui Mai is a member of technical staff at Hortonworks in the HDFS group and a core Hadoop committer. In this blog, he explains how to setup HTTPS for HDFS in a Hadoop cluster.

1. Introduction

The HTTP protocol is one of the most widely used protocols in the Internet. Today, Hadoop clusters exchange internal data such as file system images, the quorum journals, and the user data through the HTTP protocol.…

The open source community, including Hortonworks, has invested heavily in building enterprise grade security for Apache Hadoop. These efforts include Apache Knox for perimeter security, Kerberos for strong authentication and the recently announced Apache Argus incubator that brings a central administration framework for authorization and auditing.

Join Hortonworks and Voltage Security in a webinar on August 27  to learn more.

In multi-platform environments with data coming from many different sources, personally identifiable information, credit card numbers, and intellectual property can land in the Hadoop cluster.…

This summer, Hortonworks presented the Discover HDP 2.1 Webinar series. Our developers and product managers highlighted the latest innovations in Apache Hadoop and related Apache projects.

We’re grateful to the more than 1,000 attendees whose questions added rich interaction to the pre-planned presentations and demos.

For those of you that missed one of the 30-minute webinars (or those that want to review one they joined live), you can find recordings of all sessions on our What’s New in 2.1 page.…

Zettaset is a Hortonworks partner. In this guest blog, John Armstrong, VP of Marketing at Zettaset Inc., shares Zettaset’s security features and explains why data encryption is vital for data in the Hadoop infrastructure.

Comprehensive Security Across the Hadoop Infrastructure

As big data technologies like Hadoop become widely deployed in production environments, the expectation is that they will meet the enterprise requirements in data governance, operations and security while integrating with existing data center infrastructure. …

We are in the midst of a data revolution. Hadoop, powered by Apache Hadoop YARN, enables enterprises to store, process, and innovate around data at a scale never seen before making security a critical consideration. Enterprises are looking for a comprehensive approach to security for their data to realize the full potential of the Hadoop platform unleashed by YARN, the architectural center and the data operating system of Hadoop 2.

Hortonworks and the open community continue to work tirelessly to enhance security in Hadoop.…
