Hortonworks Data Platform (HDP) provides centralized enterprise services for comprehensive security to enable end-to-end protection, access, compliance and auditing of data in motion and at rest. HDP’s centralized architecture—with Apache Hadoop YARN at its core—also enables consistent operations to enable provisioning, management, monitoring and deployment of Hadoop clusters for a reliable enterprise-ready data lake.

But comprehensive security and consistent operations go together, and neither is possible in isolation.

We published two blogs recently announcing Ambari 2.0 and its new ability to manage rolling upgrades.…

The recent post by Jayush Luniya announced the community release of Apache Ambari 2.0. One of the three key Ambari features that Jayush discussed was Rolling Upgrades, enabling Hadoop operators to upgrade from one version of HDP to the next, with minimal disruption to the cluster.

The Hortonworks development team worked long and hard to make the Hadoop platform “rolling upgradeable”. That groundwork was available in Hortonworks Data Platform 2.2 as described in this previous post.…

Advances in Hadoop security, governance and operations have accelerated adoption of the platform by enterprises everywhere. Apache Ambari is the open source operational platform for provisioning, managing and monitoring Hadoop clusters from a single pane of glass, and with the Apache Ambari 1.7.0 release last year, Ambari made it far easier for enterprises to adopt Hadoop.

Today, we are excited to announce the community release of Apache Ambari 2.0, which will further accelerate enterprise Hadoop usage by simplifying the technical challenges that slow adoption the most.…

As we are finalizing our preparations for what will surely be another successful Hadoop Summit Europe event, one thing has become unequivocally clear: the Hadoop challenge is no longer about acceptance. It’s no longer about adoption. It’s about Hadoop being pervasive. Hadoop is everywhere.

As Mike Gualtieri of Forrester wrote in a recent report:

Hadoop is a must-have for large enterprises

I couldn’t agree more with Mike’s assessment, and I encourage you to read the report: “Predictions 2015: Hadoop Will Become a Cornerstone of Your Business Technology Agenda”.…

At the beginning of February, HP announced their intent to acquire Voltage Security to expand data encryption security solutions for Cloud and Big Data. Today, both companies share their thoughts about the acquisition. Carole Murphy, Director Product Marketing at Voltage Security, and Albert Biketi, Vice President and General Manager at HP Atalla, tell us more about how HP extends the capabilities of every product in the Voltage portfolio, including Voltage’s leadership in securing Hadoop data with data-centric, standards-based technologies.…

Forrester recently called Apache Hadoop adoption “mandatory” for the enterprise. For most organizations, moving forward with Hadoop is no longer a question of if, but when. Hadoop-powered insight into big data is enabling market disruption in every industry and the market winners are those who handle that data most effectively and at the lowest cost.

As with any new platform, making decisions on how best to implement and for what purpose can be challenging.…

Since our founding in 2011, Hortonworks has had a fundamental belief: the only way to deliver infrastructure platform technology is completely in open source. Moreover, we believe that collaborative open source software development under the governance model of an entity like the Apache Software Foundation (ASF) is the best way to accelerate innovation that targets enterprise end users since it brings the largest number of developers together in a way that enables innovation to happen far faster than any single vendor could achieve and in a way that is free of friction for the enterprise.…

Our guest blogger is Carole Murphy, director of product marketing for Voltage SecureStorage at Voltage Security, a Hortonworks Certified Technology Partner.

The demand for Hadoop is accelerating, as enterprises move from proof of concept to full production implementations. With the move to modern data architecture, data security and compliance has become a growing concern.

Securing data in Hadoop is a hot topic and the Hadoop community is investing and providing value-added capabilities in security and governance.…

This guest blog post is from Srikanth Venkat, director of product management at Dataguise, a Hortonworks security partner.

Plus ça change, plus c’est la même chose As Jean-Baptiste Alphonse Karr noted “The more things change, the more they stay the same.” Often, that’s not what we hear when looking at Hadoop security: people tend to call out how different Hadoop is, and how different its security solutions need to be.…

With YARN as its architectural center, Apache Hadoop continues to attract new engines to run within the data platform, as organizations want to efficiently store their data in a single repository and interact with it for batch, interactive and real-time streaming use cases. As more data flows into and through a Hadoop cluster to feed these engines, Apache Falcon is a crucial framework for simplifying data management and pipeline processing.

Falcon enables data architects to automate the movement and processing of datasets for ingest, pipeline, disaster recovery and data retention use cases.…

Introduction

Apache Ranger provides centralized security for the Enterprise Hadoop ecosystem, including fine-grained access control and centralized audit mechanism, all essential for Enterprise Hadoop. This blog covers various details of Apache Ranger’s audit framework options available with Apache Ranger Release 0.4.0 in HDP 2.2 and how they can be configured.

The audit framework can be configured to send access audit logs generated by Apache Ranger plug-ins to one or more of the following destinations:

  • RDBMS: MySQL or Oracle
  • HDFS
  • Log4j appender
Default Value xasecure.audit.is.enabled Setting to enable/disable audit logging in the Ranger plug-in.…

Hortonworks introduces HDP Operations Ready, HDP Security Ready and HDP Governance Ready certifications to showcase solutions that deeply integrate with enterprise Hadoop.

Customer adoption of Apache Hadoop continues to accelerate the pace at which the community works to meet the requirements of Enterprise Hadoop. Once the place of HDFS and MapReduce only, the introduction of Apache Hadoop YARN a little over a year ago has unleashed many new ways to get value from a Hadoop cluster.…

With Apache Hadoop YARN as its architectural center, Apache Hadoop continues to attract new engines to run within the data platform, as organizations want to efficiently store their data in a single repository and interact with it in different ways. As YARN propels Hadoop’s emergence as a business-critical data platform, the enterprise requires more stringent data security capabilities. Apache Ranger provides many of these, with central security policy administration across authorization, accounting and data protection.…

The architecture of Hortonworks Data Platform (HDP) matches the blueprint for Enterprise Apache Hadoop, with data management, data access, governance, operations and security. This post focuses on one of those core components: security. Specifically, we will focus on Apache Knox Gateway for securing access to the Hadoop REST APIs.

Pseudo Federation Provider

This blog will walk through the process of adding a new provider for establishing the identity of a user.…

With Apache Hadoop YARN as its architectural center, Apache Hadoop continues to attract new engines to run within the data platform, as organizations want to efficiently store their data in a single repository and interact with it for batch, interactive and real-time streaming use cases. More and more independent software vendors (ISVs) are developing applications to run in Hadoop via YARN. This increases the number of users and processing engines that operate simultaneously across a Hadoop cluster, on the same data, at the same time.…
