Hadoop is a Java implementation of Google MapReduce. MapReduce is a simplified distributed programming model that allows programs to be distributed automatically to a large cluster of ordinary machines. Just as Java programmers can do without memory leaks, MapReduce's run-time system solves the distribution details of input data, executes scheduling across machine clusters, handles machine failures, and manages communication requests between machines. Such a pattern allows programmers to be able to do nothing and ...
