Hive is the base component for data warehousing applications in big Data technology clusters, and is a benchmark for other similar data warehouse applications. The underlying data manipulation can be handled in a scripted manner with hive-client. If you need to develop an application, you need to connect using the JDBC driver for

0. Overview The use of CLI or Hive–e only allows the use of HIVEQL to perform queries, updates, and other operations. However, Hive also provides a client-side implementation through Hiveserver or HIVESERVER2, where the client can manipulate data in hive without starting the CLI, both allowing remote clients to use multiple programming languages such as Java, Pyt
