Apache Hive is a distributed, fault-tolerant data warehouse system that enables analytics at a massive scale. Hive Metastore(HMS) provides a central repository of metadata that can easily be analyzed to make informed, data driven decisions, and therefore it is a critical component of many data lake architectures. Hive is built on top of Apache Hadoop and supports storage on S3, adls, gs etc though hdfs. Hive allows users to read, write, and manage petabytes of data using SQL.
Apr 25, 2023 · Apache Hive is a data warehouse software project that is built on top of the Hadoop ecosystem. It provides an SQL-like interface to query and analyze large datasets stored in Hadoop’s distributed file system (HDFS) or other compatible storage systems. Hive uses a language called HiveQL, which is similar to SQL, to allow users to express data queries, transformations, and analyses in a familiar syntax. HiveQL statements are compiled into MapReduce jobs, which are then executed on the Hadoop ...
Apache Hive is a data warehouse software project. It is built on top of Apache Hadoop for providing data query and analysis. [3] [4] Hive gives an SQL-like interface to query data stored in various databases and file systems that integrate with Hadoop.
Hive Tutorial. Hive tutorial provides basic and advanced concepts of Hive. Our Hive tutorial is designed for beginners and professionals. Apache Hive is a data ware house system for Hadoop that runs SQL like queries called HQL (Hive query language) which gets internally converted to map reduce jobs.
Hive includes HCatalog, which is a table and storage management layer that reads data from the Hive metastore to facilitate seamless integration between Hive, Apache Pig, and MapReduce. By using the metastore, HCatalog allows Pig and MapReduce to use the same data structures as Hive, so that the metadata doesn’t have to be redefined for each engine.

Feb 23, 2021 · What Is Hive. Hive is a data warehousing infrastructure based on Apache Hadoop. Hadoop provides massive scale out and fault tolerance capabilities for data storage and processing on commodity hardware. Hive is designed to enable easy data summarization, ad-hoc querying and analysis of large volumes of data. It provides SQL which enables users to do ad-hoc querying, summarization and data analysis easily. At the same time, Hive's SQL gives users multiple places to integrate their own ...
