What is Apache Hive?

Apache Hive is a data warehousing and SQL-like query language for Apache Hadoop, a framework used for distributed storage and processing of large data sets. It provides a way to extract insights from data stored in Hadoop's HBase or other distributed file systems such as HDFS.

Key Features of Apache Hive include its ability to translate SQL-like queries into MapReduce jobs, which can then be executed on the Hadoop cluster. This allows users to leverage the scalability of Hadoop without needing to write complex Java code for MapReduce.

  • Data Definition: Hive allows users to define the schema of their data, making it easier to manage and query large datasets.

  • Query Execution: Hive can execute queries on data stored in Hadoop, providing a way to analyze and extract insights from the data.
