Hadoop Developer 3-Day Course
Tuesday, December 20, 2011 at 9:00 AM - Thursday, December 22, 2011 at 5:00 PM (CST)
Think Big, Start Smart, Scale Fast
Hadoop Developer 3-Day Course
The Hadoop Developer 3-Day Course presented by Think Big Academy is designed to make you productive with Hadoop. The topics of this course reflect our experience building Hadoop analytics applications with clients. Once your Hadoop cluster is up and running, you can transition existing data management applications over to Hadoop. Explore new ways to use Hadoop and unstructured data and learn the comprehensive capabilities now available across the Hadoop ecosystem.
The following prerequisites ensure that you will gain the maximum benefit from the course.
- Programming experience: This is developers course. We will write Java, Hive, and Pig applications. Prior Java experience is recommended.
- Linux shell experience (recommended): Basic Linux shell (bash) commands will be used extensively.
- Experience with SQL databases (optional): SQL experience is useful for learning Hive and Pig, but not essential.
What You Must Bring
Bring your laptop with the following software installed.
- VMWare or VirtualBox: A virtual machine (VM) will be provided for running the course exercises. Your laptop must have the freeware VirtualBox (https://www.virtualbox.org/) or a licensed copy of VMWare (http://www.vmware.com/products/workstation/) installed to run the virtual machine.
- JDK 1.6: The JDK (Java Development Kit) version 1.6 or newer is required (not just the JRE - Java Runtime Environment). (http://www.oracle.com/technetwork/java/javase/downloads/index.html)
- Ant: The Java-based ant build tool, version 1.7 or newer, will be used to build and test the exercises. (http://ant.apache.org/)
- A programmer's source code editor: Whatever you prefer. Either Eclipse or IntelliJ IDEA is recommended and project files for both environments will be provided.
- Cygwin (Windows systems): Laptops running Windows must have the Cygwin environment installed, including the open-ssl module (discussed next). (http://www.cygwin.com/)
- Secure shell (ssh) software: for example, OpenSSL or a GUI secure shell application. Each computer will need the ability to use
sshto log into the provided virtual machine used for the course. The related
scp(secure copy) command must also be available for transferring files between environments.
- The Academy courseware: Several days before the class, Think Big Academy will provide a courseware package including the virtual machine used for the course, the course exercises, installation instructions, etc. Please install this package before the first day of class!
What You Will Learn
Think Big Academy courses teach by doing, where short lectures and hands-on exercises are interspersed. By the end of the course, you will learn the following:
- The components of the Hadoop ecosystem and how they work together.
- The basics of installing and configuring Hadoop.
- The MapReduce programming model and the problems it solves.
- The Hadoop Distributed File System (HDFS).
- How to use the Hadoop command line tools and the web consoles.
- How to create Hadoop applications using the MapReduce Java and Streaming APIs.
- How to create Hadoop applications using Hive and Pig.
- How to create custom extensions for Hive and Pig and MapReduce.
- The roles of other Hadoop ecosystem tools, including HBase, data ingestion tools, data integration tools, job scheduling techniques, and monitoring options.
- Common pitfalls and problems, and how to avoid them.
- Lessons from real-world Hadoop implementations.
