(Hive is used as a data warehouse tool, and the underlying computing is implemented by a distributed computing framework. Currently, Hive supports three computing engines, namely MapReduce, Tez and Spark. Hive's default computing engine is MapReduce, which is controlled by the hive.execution.engine parameter property.
The course is oriented to the development and tuning of Hive3.X, in-depth Hive source-level teaching, allowing students to learn higher-level technologies. At the end of the course, the training content related to Hive interviews is also included, so that students will no longer be afraid when encountering related interview questions.)
