Hadoop. The very word is starting to generate gut reactions, which may be positive or negative. Polarized viewpoints are becoming common. Hadoop family components include its distributed file system, encompassing an IP range of storage, replicating each record of data in 3 strategic places across the file system and tracking the distribution centrally. It also includes the MapReduce algorithm for processing distributed data by processing it as locally as possible. Hadoop horizontally scales across dozens, hundreds or thousands of servers.
