Getting Started - Enterprise Data Workflows with Cascading - page 1

CHAPTER 1
Getting Started
Programming Environment Setup
The following code examples show how to write apps in Cascading. The apps are in‐
tended to run on a laptop using Apache Hadoop in standalone mode, on a laptop run‐
ning Linux or Unix (including Mac OS X). If you are using a Windows-based laptop,
then many of these examples will not work, and generally speaking Hadoop does not
behave well under Cygwin. However, you could run Linux, etc., in a virtual machine.
Also, these examples are not intended to show how to set up and run a Hadoop cluster.
There are other good resources about that—see Hadoop: The Definitive Guide by Tom
White (O'Reilly).
First, you will need to have a few platforms and tools installed:
Java
• Version 1.6.x was used to create these examples.
• Get the JDK, not the JRE.
• Install according to vendor instructions.
Apache Hadoop
• Version 1.0.x is needed for Cascading 2.x used in these examples.
• Be sure to install for “Standalone Operation.”
Gradle
• Version 1.3 or later is required for some examples in this topic.
• Install according to vendor instructions.
