Objectives

Through instructor-led discussion and interactive, hands-on exercises, participants will navigate the Hadoop ecosystem, learning topics such as:

• The use cases and usage occasions for HBase, Hadoop, and RDBMS
• Using the HBase shell to directly manipulate HBase tables
• Designing optimal HBase schemas for efficient data storage and recovery
• How to connect to HBase using the Java API to insert and retrieve data in real time
• Best practices for identifying and resolving performance bottlenecks

Public

This course is appropriate for developers and administrators who intend to use HBase.

Prerequisites

Prior experience with databases and data modeling is helpful, but not required.
Knowledge of Java is assumed.
Prior knowledge of Hadoop is not required, but Cloudera Developer Training for Apache Hadoop provides an excellent foundation for this course.
