Hadoop is an open-source implementation of the MapReduce framework.It is hosted at the Apache Software Foundation along with a numberof supporting software projects, including the Hadoop DistributedFile System (HDFS) and Pig programming language. MapReduce and Hadoop are based on the principle of splitting uplarge amounts of data and then processing the chunks in parallelacross large numbers of nodes. It's closely associated with theindustry buzzword "big data," which refers to the ever-largervolumes of information, particularly of unstructured form, beinggenerated by websites, social media, sensors and other sources. Overall, Hadoop has enjoyed a steady stream of interest fromcommercial analytics and database vendors in recent years, who havebegun offering commercial products and services for it.

While "fantastic and largely unsupportable claims have been made"regarding Hadoop and MapReduce's use cases and benefits, "there canbe no doubt that it does provide a relatively low-cost means ofderiving considerable value from very large collections ofunorganized data," IDC analysts Carl Olofson and Dan Vesset wrotein the report. Therefore, the conditions are right for significant growth in theHadoop-MapReduce "ecosystem," according to IDC. This year, "Leading adopters in the mainstream IT world will movefrom 'proof of concept' to real value," the report states. However, lack of qualified talent will limit the technology's riseduring the next two to three years, it adds. The coming years will also see a "battle between open sourcepurists, who believe that the core of Hadoop deployment must bebased purely on the Apache project code," according to IDC.However, most IT organizations will use a mix of commercial andopen-source components in their Hadoop environments, the reportadds.

Still, "competition between open source vendors and their closedsource counterparts may force lower license fees from the lattergroup, resulting in somewhat slower software revenue growth than would be the case if open sourceprojects did not represent so large a component of this marketspace."
