In addition to the points below about Hadoop's implementation of MapReduce, Hadoop consists of many subprojects which perform complex tasks: HDFS, a reliable, petabyte-scale distributed file system; HBase, a clone of Google's BigTable; Pig and Hive, which provide higher-level syntax, columnar storage in HDFS, and a persistent metadata repository; and Zookeeper, a coordination service for distributed systems.

I'm not impressed by how REvolution's new management is approaching marketing.

sorry to sound trollish, but the sad part is that this sort of marketing-speak masquerading as technical blogging might actually be able to earn companies 'streed cred' with customers. their potential clients might be like "oh wow you guys really CAN implement Google's famous MapReduce or Yahoo's Hadoop in a few lines of R, and you even wrote about it on a techie blog, we'll buy it!"
