Beeline is a command-line interface (CLI) for interacting with Apache Hive, an open-source data warehouse system built on top of Hadoop. It is an alternative to the original Hive CLI, which has some limitations and can be difficult to use. Beeline provides a more modern and flexible interface for interacting with Hive.
One of the main benefits of Beeline is that it supports multiple authentication mechanisms, including Kerberos, LDAP, and SSL. This makes it more secure than the original Hive CLI. Beeline also supports multiple output formats, including CSV, TSV, and JSON, making it easier to integrate with other tools and systems.
In addition, Beeline supports multiple sessions, which means that you can connect to multiple Hive instances simultaneously and switch between them easily. It also supports tab completion and history, making it easier to navigate and recall previously entered commands.
Overall, Beeline is a powerful tool for interacting with Hive and is becoming increasingly popular as an alternative to the original Hive CLI. Its modern interface, support for multiple authentication mechanisms and output formats, and other features make it a more flexible and convenient option for working with Hive.
