Apache Hive is a data warehouse system used for processing and managing large datasets residing in distributed storage systems such as Hadoop Distributed File System (HDFS). Hive provides a mechanism to project a structure onto this raw data and query the data using SQL statements. Hive dates back to 2008 when Facebook developed it to handle the increasing volume of data used internally by the social media platform. Facebook's data engineers observed that SQL was a common language for data analysts and business analysts and, therefore, sought to create a system that used SQL to query data stored in Hadoop. Apache Hive was open-sourced in 2010. Because Hive uses SQL as an interface language for performing queries, users can access Hadoop data without needing a programming environment.

Hive is designed to work with large datasets residing in distributed file systems. It enables big data processing and analysis in a scalable environment. Hive queries, written in SQL, are translated into MapReduce jobs that are executed in Hadoop. Users interact with Hive using HiveQL, a dialect of SQL that includes extensions to support data manipulation in a Hadoop environment.
