HBase For Developers

Overview:

This course introduces HBase – a NoSQL store on top of Hadoop.  The course is intended for developers who will be using HBase to develop applications,  and administrators who will manage HBase clusters.

What You Will Learn:

  • HBase architecture and design
  • HBase internals
  • Using APIs to interact with HBase
  • Data modeling on HBase


Duration :

3 days

Audience :

Developers  & Administrators

Prerequisites :

  • comfortable with Java programming language
  • comfortable in Java programming language (navigate Linux command line , edit files with vi / nano)
  • A Java IDE like Eclipse or IntelliJ

 

Lab environment:

A working HBase cluster will be provided for students.  Students would need a SSH client and a browser to access the cluster.

Zero Install : There is no need to install HBase software on students’ machines!
