Apache Pig
Hadoop is a powerful framework. The processing of data in Hadoop is achieved by
MapReduce, which is a Java-based framework. All MapReduce applications are written in
Java. To make it easier for non-Java programmers to work with Hadoop, Yahoo! developed
a platform known as Pig.
Pig, a top-level Apache project, provides a simple high-level scripting language called
Pig
Latin
, which allows users to write intuitive scripts to process data stored in HDFS.
Internally, Pig Latin is converted to several MapReduce jobs to process the data in HDFS.
Pig is an abstraction over MapReduce.
