Computing efficiency is important not only for speed-up and scale-out performance but also power consumption. Consider a hypothetical High-Performance Computing (HPC) system of 10,000 nodes running 50% idle at 50 watts per idle node, and assuming 10 cents per kilowatt hour ... Read More

Webinar : December 8th, 10-11:00am PT, 1-2:00pm ET Presenter: Eric Sammer, Cloudera Solution Architect Many Apache Hadoop deployments begin as small test clusters as either an electronic sandbox for analyzing data in new ways or solving a small specific business problem.

Typically one or more of the use cases provides insight that is critical to the efficient operation of business and eventually creates a need for ... Read More

Feed: Latest imported feed items on Analytics Matters. What’s it worth? During a recent business-value consulting engagement with a global telecom company, the CEO told me he believed that the investments he was making in enterprise information assets were generating huge value. The only problem was he could see no evidence of it other than the retained revenue and revenue growth reported by his marketing team. Shortly after, the director of BI and analytics confided that, in his opinion, the advanced analytics team was a lot more valuable than the company’s information assets, and wanted to know if there a ...

Feed: Big Data Made Simple - One source. Many perspectives.. Author: Baiju NT. With the plethora of devices connecting to the Internet, companies are collecting information from consumers continuously. Even though companies’ data storage capacity is growing daily at enormous rates, there are inadequate solutions for security issues to protect that data. The big data that companies store and process is very sensitive. This data is subject to the same compliance mandates and requires the same protection against breaches as with traditional databases.

Feed: Cloudera Engineering Blog » Hadoop. Author: Arvind Prabhakar. Hadoop has emerged as an indispensable component of any data-intensive enterprise infrastructure.  In many ways, working with large datasets on a distributed computing platform (powered by commodity hardware or cloud infrastructure) has never been easier. But because customers are running clusters consisting of hundreds or thousands of nodes, and are processing massive quantities of data from production systems every hour, the logistics of efficient platform utilization can quickly become overwhelming. To deal with this challenge, the Yahoo! engineering team created Oozie – the Hadoop workflow engine. We are pleased to provide ... Read More
