Implementing a Pig action job using Oozie
In this recipe, we are going to take a look at how to use a Pig action in order to automate the Pigscripts executions.
Getting ready
To perform this recipe, you should have a running Hadoop cluster as well as the latest version of Oozie and Pig installed on it.
How to do it...
A Oozie job execution consists of two important things, workflow.xml and a properties file. The workflow.xml file is where we need to specify the flow of execution. The following is an example of workflow.xml, which uses the Pig action:
<workflow-app xmlns="uri:oozie:workflow:0.2" name="pig-wf"> <start to="pig-node"/> <action name="pig-node"> <pig> <job-tracker>${jobTracker}</job-tracker> <name-node>${nameNode}</name-node> <prepare> <delete ...Get Hadoop: Data Processing and Modelling now with the O’Reilly learning platform.
