joins in chapter 5. Pig is a Hadoop extension that simplifies Hadoop programming by giving you a high-level data processing language while keeping Hadoop's simple scalability and reliability. Yahoo , one of the heaviest user of Hadoop (and a backer of both the Hadoop Core and Pig), runs 40 percent of all its Hadoop jobs with Pig.

To perform the analysis structural data, we are using hadoop Apache Pig software and its native language Pig-latin that comes intrigated with Hadoop's Apache Pig software. How to Run Pig To run the Pig environment, we have to enter in grunt interactive shell. This shell can be initiated in two different modes using the following commands -

Foundation in 2007. Pig consists of a language and an execution environment. Pig's language, called as PigLatin, is a data flow language - this is the kind of language in which you program by connecting things together. Pig can operate on complex data structures, even those that can have levels of nesting. Unlike SQL, Pig does not require that

It includes a language, Pig Latin, for expressing these data flows. Pig Latin includes operators for many of the traditional data operations (join, sort, filter, etc.), as well as the ability for users to develop their own functions for reading, processing, and writing data.
