Feed: Cloudera Engineering Blog » Hadoop. Author: Jon Zuanich. Neil Kodner, an independent consultant, is the guest author of this post. Neil found inspiration, which spurred innovation at Hadoop World 2010 from a moments decision to capture the #hw2010 streaming Twitter feed. During the Hadoop World 2010 keynote, a majority of attendees were typing away on their laptops as Mike Olson and Tim O’Reilly dazzled the audience.  Many of these laptop-users appeared to be tweeting as the keynote was taking place.   Since I have more than a passing interest in twitter, Hadoop, and text mining, I thought it would be a great ...

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: Cloudera Engineering Blog » Hadoop. Author: Alex Kozlov. Apache Hadoop and Apache HBase are gaining popularity due to their flexibility and tremendous work that has been done to simplify their installation and use.  This blog is to provide guidance in sizing your first Hadoop/HBase cluster.  First, there are significant differences in Hadoop and HBase usage.  Hadoop MapReduce is primarily an analytic tool to run analytic and data extraction queries over all of your data, or at least a significant portion of them (data is a plural of datum).  HBase is much better for real-time read/write/modify access to tabular data.  Both ...

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
