Apache Software Foundation announces Apache® Hive 4.0

Open source data warehouse software built on top of Apache Hadoop enables data analytics and management at massive scale 

The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 320 open-source projects and initiatives, today announced Apache Hive 4.0. For over a decade, Apache Hive has been the cornerstone of data warehouse and data lake architectures, empowering companies and organizations worldwide to perform analytics at an unprecedented scale while seamlessly managing vast amounts of data through SQL queries.

Since its inception in 2010 Apache Hive has evolved to meet the ever-growing demands of modern data management by offering a distributed, fault-tolerant data warehouse system known for its scalability and reliability. With support for Kerberos authentication and seamless integration with Apache Ranger and Apache Atlas for enhanced security and observability, Hive has become one of the best go-to solutions for enterprises seeking robust data management solutions.

“Hive 4.0 is one of the most significant releases from the Hive community to-date, unlocking unprecedented capabilities for data engineers, analysts and architects who need to manage or analyze data at scale,” said Ayush Saxena, ASF Member and Hive contributor. “This release is the result of a tremendous effort from the Hive community, and we are excited to announce its availability.” 

Empowering the Data Ecosystem
At the heart of Apache Hive lies the Hive Metastore (HMS), a centralized repository of metadata that serves as a fundamental building block for data lakes. Hive leverages a myriad of open source technologies including Apache Spark, Presto, and Trino. The Hive Metastore facilitates seamless access to metadata for various clients including Hive, Apache Impala and Spark, making it a vital component of the modern data ecosystem.
