Learners explore working with complex data types in Apache Hive in this Skillsoft Aspire course, which assumes previous work with Hive tables using the Hive query language, and comfort using a command-line interface or Hive client to run queries. Learners begin this 12-video, hands-on course by working with Hive tables whose columns are of complex data types (arrays, maps, and structs). Watch demonstrations of set operations and transforming complex types into tabular form with explode operation. Then use lateral views to add more data to exploded outputs. Course labs use the Beeline client; the instructor's Beeline terminal runs on the master node of a Hadoop cluster, provisioned on Google Cloud platform using its Dataproc service, and learner access is assumed to a Hadoop cluster and Beeline, on-premises or in the cloud. Finally, learners observe how to use views to aggregate contents of multiple columns. As the course concludes, you should be comfortable working with all types of data in Hive and performing analysis tasks on tables with both parameter types as well as complex data.
