Pig is generally used with Hadoop; we can perform all the data manipulation operations in Hadoop using Apache Pig. Pig is a high-level data flow platform for executing Map Reduce programs of Hadoop. Apache Pig is extensible so that you can make your own user-defined functions and process. These files work with Hadoop 0.18 and provide everything you need to run the Pig scripts. Similar to Pigs, who eat anything, the Pig programming language is designed to work upon any kind of data.

The language for Pig is pig Latin.

(or) ORDER BY operator is used to sort the data in ascending or descending order, based on one or more columns.Some data … Several operators are provided by Pig Latin using which personalized functions for writing, reading, and processing of … clean1 = FILTER raw BY org.apache.pig.tutorial.NonURLDetector(query); Call the ToLower UDF to change the query field to lowercase.

Apache Pig Order By - The ORDER BY operator is used to display the contents of a relation in a sorted order based on one or more fields.

This Apache Pig tutorial provides the basic introduction to Apache Pig – high-level tool over MapReduce.. Apache Pig Tutorial. Join operation is easy in Apache Pig. This tutorial helps professionals who are working on Hadoop and would like to perform MapReduce operations using a high-level scripting language instead of developing complex codes in Java.

The salient property of Pig programs is that their structure is amenable to substantial parallelization, which in turns enables them to handle very large data sets. Features of Apache Pig: For performing several operations Apache Pig provides rich sets of operators like the filters, join, sort, etc. Pig’s simple SQL-like scripting language is called Pig Latin, and appeals to developers already familiar with scripting languages and SQL. Pig is generall Apache Pig is a platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs.
Watch this video on ‘Apache Pig Tutorial’: For writing data analysis programs, Pig renders a high-level programming language called Pig Latin.

clean2 = FOREACH clean1 GENERATE user, time, org.apache.pig.tutorial.ToLower(query) as query; Because the log file only contains queries for a single day, we are only interested in the hour. Watch this video on ‘Apache Pig Tutorial’: For writing data analysis programs, Pig renders a high-level programming language called Pig Latin. The Pig tutorial file (pigtutorial.tar.gz) or the tutorial/pigtutorial.tar.gz file in the pig distribution) includes the Pig JAR file (pig.jar) and the tutorial files (tutorial.jar, Pigs scripts, log files). Similar to Pigs, who eat anything, the Pig programming language is designed to work upon any kind of data. Pig runs in two execution modes: Local and MapReduce. Apache Pig enables people to focus more on analyzing bulk data sets and to spend less time writing Map-Reduce programs. It is designed to provide an abstraction over MapReduce, reducing the complexities of writing a MapReduce program.
