Abstract: |
The solution of Hadoop & MapReduce and their associated applications includes among others a simple but very powerful method for the processing and analysis of extremely large data sets, even up to the level of multiple PetaBytes. At its core, MapReduce is a process for combining data from multiple inputs (creating the "map"), and then reducing (reduce) it using a function that will refine the desired results. This chapter presents multiple use cases of Hadoop & MapReduce and their applications for multi-TB and even multi-PB instances; Hadoop uses a distributed file system, HDFS. The Hadoop/MapReduce system is useful for data that is less structured such as Internet pages or multiple document or image data that is not fully organized-structured.
