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
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

Hive is just a client, and in production it is not necessary to deploy the cluster
There are several major classes of hive clients:-Hive-WebUI: Operation of hive tab
Hive with the JDBC ExampleWhen developing a hive program using JDBC, you must first turn on the remote service interface for hive. Under the Hive installation directory, use the following command to open the bin:Hive-service Hives

Due to the requirements of recent projects, the function of implementing HQL statements in command line mode using hive JDBC encoding is studied carefully. During the period, we encountered a lot of problems, and analyzed and solved them. But time was in a hurry, and I was unable to record the problems I had encountered. With 00 sparse memories, these questions and experiences are expected to be summed up f
