The most significant new feature in Apache Hive 2, to be included in the upcoming HDP 2.5 release is a technical preview of LLAP (Live Long and Process). LLAP enables as fast as sub-second SQL analytics on Hadoop by intelligently caching data in memory with persistent servers that instantly process SQL queries. Since LLAP is […]

Accelerated Threat Triage and Expanded Deployment Options Two months ago, the Metron Engineering and PM team  released  Technical Preview 1 of Apache Metron based on the 0.1 release. We shared our vision for an open community based cybersecurity solution that provides real-time, cross-referenced and contextualized big data to combat cyber threats. Apache Metron Reference Architecture As the above […]

Debugging distributed systems can be difficult largely because they are designed to run on many (possibly thousands) of hosts in a cluster. This process typically involves monitoring and analyzing log files spread across the cluster, and if the necessary information is not being logged, service restarts and job redeployment may be required. Not only is […]

In Part 3 of the Apache Metron announcement series, Apache Metron Tech Preview 1 – Come and Get it! , we outlined Apache Metron 0.1 release’s new features and enhancements. Then we demonstrated how to deploy on a single node VM using vagrant and a cloud-based install for a complete 10 node Metron cluster using […]

Hello from the Metron PM and Engineering Team Over the last few months, you may have read a series of blogs written by the Metron Product Management and Engineering teams on CyberSecurity and Analytics and the role that Big Data / Hadoop / HDP plays in this space. In December 2015, James Sirota, Director of Security Solutions […]

I recently discussed the future of data with Arun Murthy, one of the founders of Hortonworks.   The good news is that, not only is the technology available, but Hortonworks customers are already getting competitive advantage from their data right now.   The dream that Arun and the other founders had when they created Hortonworks of […]

Hortonworks launched SmartSense in 2015 to help customers quickly collect cluster configuration, metrics, and logs to proactively detect issues, and expedite support cases troubleshooting.  This diagnostic information is packaged into an encrypted and anonymized bundle and sent to Hortonworks for analysis.  The result of that analysis is available as customized recommendations to help prevent issues […]

HDFS is core part of any Hadoop deployment and in order to ensure that data is protected in Hadoop platform, security needs to be baked into the HDFS layer. HDFS is protected using Kerberos authentication, and authorization using POSIX style permissions/HDFS ACLs or using Apache Ranger. Apache Ranger (http://hortonworks.com/hadoop/ranger/) is a centralized security administration solution […]

Hackathons, Hackfest, and Codefests have an initial air of invincibility. They challenge participants, even veterans—not if the attendees work together or if the community collaborates and innovates together. That air of invincibility quickly dissipates. Last Saturday, because of such camaraderie and collaboration, a harmony of innovative ideas flourished and came to fruition at an Ambari […]
