The release of Hadoop 2 seems to be all that prospective users and industry analysts can talk about. If you think all that chatter has translated into widespread adoption, you're wrong. The release -- a possible answer to calls for a "hardened" Hadoop -- adds features that enable users to expand the open source distributed processing framework beyond its original core configuration of MapReduce and the Hadoop Distributed File System.

In this handbook, IT managers, data management staffers and other readers will benefit from in-depth analysis of the new capabilities, potential uses and limitations of Hadoop 2 and related technologies. For readers still unsure about what to do with the open source software, this handbook offers insight into Hadoop 2 -- complete with a close look at YARN, Hadoop's redesigned resource manager.   Access >>>
