What is Hadoop?
Hadoop was created by Doug Cutting and Mike Cafarella in the year 2005. Doug Cutting named the framework after his child’s stuffed yellow toy elephant. Doug used the name for his open source project because it was relatively easy to spell, pronounce and meaningless.
Beginning in the 1930s, this timeline covers the explosion of information and how Big Data has created the need to organize and save information. Big data is a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications.
Today, 1,000 Facebook employees use Presto to crunch a petabyte (as in 1,000,000 gigabytes) of data every single day. As data increasing every day we need Hadoop to scale up from a single server to thousands of machines, with very high degree of fault tolerance. Rather than relying on high-end hardware, the resiliency of these clusters comes from the software's ability to detect and handle failures at the application layer.
