Working with text is a common usage of the MapReduce process, because text processing is relatively complex and processor-intensive processing. The basic word count is often used to demonstrate Haddoop's ability to handle large amounts of text and basic summary content. To get the number of words, split the text from an input file (using a basic string tokenizer) for each word that contains the count, and use a Reduce to count each word. For example, from the phrase the quick bro ...

With the development and application of large data in various business areas, relevant technologies and tools are emerging, in which the Hadoop framework receives more attention and application. "Don't underestimate the value of relational database technology," says Ken Rudin, a Facebook analyst, who recently delivered a keynote address at a strata+hadoop World Congress in New York. 　　He argues that the Hadoop programming framework may be synonymous with the "Big data" movement, but it is not the only tool for an enterprise to gain value from unstructured information stored on a large scale.

Rudin says Facebook's business model relies on its handling of user information and activity data for more than 1 billion social media users ...
