Advanced Hadoop for Developers

Overview

Apache Hadoop is one of the most popular frameworks for processing Big Data on clusters of servers.  This course focuses on advanced programming techniques that will be beneficial to experienced Hadoop developers.

What You Will Learn

  • Advanced Pig
  • Advanced Hive
  • Advanced HBase (SQL)

Audience:

Developers

Duration:

three days

Format:

lectures (50%) and hands-on labs (50%).

Prerequisites

  • comfortable with Java programming language (most programming exercises are in java)
  • comfortable in Linux environment (be able to navigate Linux command line, edit files using vi / nano)
  • attended “Hadoop for Developers” or has working  knowledge of Hadoop.

Lab environment

Zero Install: There is no need to install hadoop software on students’ machines! A working hadoop cluster will be provided for students.

Students will need the following

  • a SSH client (Linux and Mac already have ssh clients, for Windows Putty is recommended)
  • a browser to access the cluster. We recommend Firefox browser
