The latest Apache HBase releases, 0.92 and 0.94, contain many improvements over prior releases in terms of correctness and performance improvements. We discuss a couple of these improvements from a development and operations perspective.
All Your Base AWS has already given you a lot of storage and processing options to choose from, and today we are adding a really important one. You can now use Apache HBase to store and process extremely large amounts...

Knowing what your users are doing on your site in real time and matching what they do with more targeted information transforms into better conversion rate and better user satisfaction, which means more money in the end.
Big data is among the hottest trends in IT right now, and Hadoop stands front and center in the discussion, but many people don’t seem to know exactly what it means when somebody says “Hadoop.”
Like a kid waiting for Christmas to come, I have been watching the Mahout project with great anticipation. When you toss around the concepts of map/reduce and machine learning, there's an awful lot of potential for radical ninjas to ensue. While the magical science-fiction world of artificial intelligence is still in a fetal state within our reality, it is, nonetheless, a growing science

2down.us download NowBook DescriptionDiscover how Apache Hadoop can unleash the power of your data. This comprehensive resource Shows you how to build and maintain reliable, scalable, distributed systems with the Hadoop framework - an open source implementation of MapReduce, the algorithm on which Google built its empire. Programmers will find details for analyzing datasets of any size, and administrators will learn how to set up and run Hadoop clusters.This revised edition covers recent changes to Hadoop, including new features such as Hive, Sqoop, and Avro. It also provides illuminating case studies that illustrate how Hadoop is used to solve specific problems. Looking to get the most out of your data? This is your book. * Use the Hadoop Distributed File System (HDFS) for storing large datasets, then run distributed computations over those datasets with MapReduce * Become familiar with Hadoop's data and I/O building blocks for compression, data integrity, serialization, and persistence * Discover common pitfalls and advanced features for writing real-world MapReduce programs * Design, build, and administer a dedicated Hadoop cluster, or run Hadoop in the cloud * Use Pig, a high-level query language for large-scale data processing * Analyze datasets with Hive, Hadoop's data warehousing system * Take advantage of HBase, Hadoop's database for structured and semi-structured data * Learn ZooKeeper, a toolkit of coordination primitives for building distributed systems"Now you have the opportunity to learn about Hadoop from a master - not only of the technology, but also of common sense and plain talk."-Doug Cutting, ClouderaAbout the AuthorTom White has been an Apache Hadoop committer since February 2007, and is a member of the Apache Software Foundation. He works for Cloudera, a company set up to offer Hadoop support and training. Previously he was as an independent Hadoop consultant, working with companies to set up, use, and extend Hadoop. He has written numerous articles for O'Reilly, java.net and IBM's developerWorks, and has spoken at several conferences, including at ApacheCon 2008 on Hadoop. Tom has a Bachelor's degree in Mathematics from the University of Cambridge and a Master's in Philosophy of Science from the University of Leeds, UK.Book Details * Paperback: 624 pages * Publisher: O'Reilly Media; 2 edition (October, 2010) * Language: English * ISBN-10: 1449389732 * ISBN-13: 978-1449389734Download files from Hotfile : Code: http://hotfile.com/dl/73147882/2bd91....2010.rar.htmlDownload files from Fileserve : Code: http://www.fileserve.com/file/K6m3zsp2down.us Download Now
Over the last few years, state-sponsored data collection has come to the fore thanks to whistle-blowers and ex-spies. Since then, the clamor for calling the line between private and public data for...
When designing schemas for HBase, be it from scratch or porting an existing application over from a relational database for example, there are a set of architectural constraints that a user should be aware of to avoid common pitfalls.
The question posed at this week’s San Francisco Hadoop User Group is a common one: “what factors justify the use of an Apache Hadoop cluster vs. traditional approaches?” The answer you receive depends on who you ask.
I wanted to do some experimenting with various tools for doing Hadoop and HBase activities and didn’t want to have to bother making it work with our Cluster in the Cloud. I just wanted a simple experimental environment on my Macbook Pro running Snow Leopard Mac OS X.
