Description

Apache Hadoop is a set of algorithms for distributed storage and distributed processing of Big Data on computer clusters built from commodity hardware. All the modules in Hadoop are designed with a fundamental assumption that hardware failures are commonplace and thus should be automatically handled in software by the framework. In this course, you'll explore Hive as a SQL like tool for interfacing with Hadoop. The course demonstrates the installation and configuration of Hive, followed by demonstration of Hive in action. Finally, you'll learn about extracting and loading data between Hive and a RDBMS. This learning path can be used as part of the preparation for the Cloudera Certified Administrator for Apache Hadoop (CCA-500) exam.
