Pig (or PIG-latin) is a MapReduce programming language used with Hadoop. The language abstracts the programming from the Java MapReduce idiom, into a notation which makes MapReduce programming high level, similar to that of SQL for RDBMS systems. The PIG programming language can be extended using UDF (User Defined Functions) which the user can write in Java and then call directly from the language.
