It is estimated that by 2015, more than half of the world's data will involve hadoop--an increasingly large ecosystem around the open source platform, a powerful confirmation of this alarming figure. However, some say that while Hadoop is the hottest topic in the bustling Big data field right now, it is certainly not a panacea for all the challenges of data center and data management. With this in mind, we don't want to speculate about what the platform will look like in the future, nor do we want to speculate about what the future of open source technology will be for radically changing data-intensive solutions.

While Hadoop is the hottest topic in the bustling Big data field right now, it is certainly not a panacea for all the challenges of data center and data management. 　　With that in mind, we don't want to speculate about what the platform will look like in the future, nor do we want to speculate on the future of open source technology for various data-intensive solutions, but instead focus on real-world applications that make Hadoop more and more hot. One of the cases: ebay's Hadoop environment ebay Analytics Platform Development Group Anil Madan discusses how the auction industry's giants are charging ...
