About this course

Targeted towards data architects and application developers who have experience with Java, the goal of this course is to learn how to write HBase programs using Hadoop as a distributed NoSQL datastore. This first course in the HBase Java API series teaches the most important APIs for writing HBase programs, how to use the Java API to perform CRUD operations, use helper classes, create and delete tables, set and alter column family properties, and batch updates. Concepts are conveyed through lectures, hands-on labs and analysis of scenario. This course builds on DEV 320 and 325 – HBase Data Model and Schema Design, which gives the foundations of HBase architecture, the HBase data model, and schema design.
