What is Hive?

Hive is a component of Hortonworks Data Platform(HDP). Hive provides a SQL-like interface to data stored in HDP. In the previous tutorial we used Pig which is a scripting language with a focus on dataflows. Hive provides a database query interface to Apache Hadoop.

Apache Hive is a data warehouse infrastructure built on top of Hadoop for providing data summarization, query, and analysis.While initially developed by Facebook, Apache Hive is now used and developed by other companies such as Netflix.Amazon maintains a software fork of Apache Hive that is included in Amazon Elastic MapReduce on Amazon Web Services.

Apache Hive supports analysis of large datasets stored in Hadoop's HDFS and compatible file systems such as Amazon S3 filesystem. It provides an SQL-like language called HiveQL with schema on read and transparently converts queries to map/reduce, Apache Tez and Spark jobs. All three execution engines can run in Hadoop YARN. To accelerate queries, it provides indexes, including bitmap indexes.
