Apache pig – architecture. Language for analyzing data Hadoop use pig is called pig Latin. It is a high-level data processing language that provides a rich set of data types and operators to perform various operations on data.
Some people also ask, what is the difference between Pig and Hive?
1) Hive Hadoop components are mainly used by data analysts, while Pig Hadoop Components are commonly used by researchers and programmers. 2) Hive Hadoop components are used for fully structured data, while Pig Hadoop Components are used for semi-structured data.
