This course is designed for administrators who will be installing, configuring and managing HBase clusters. It covers installation with Ambari, configuration, security and troubleshooting HBase implementations. The course includes an end-of-course project in which students work together to design and implement an HBase schema.
PREREQUISITES
Students must have the basic familiarity with data management systems. Familiarity with Hadoop or databases is helpful but not required. Students new to Hadoop are encouraged to take the
HDP Overview: Apache Hadoop Essentials course.
TARGET AUDIENCE
Architects, software developers, and analysts responsible for implementing non-SQL databases in order to handle sparse datasets commonly found in big data use cases.
FORMAT
50% Lecture/Discussion
50% Hands-on Labs
