Implementing an e-mail action job using Oozie
In this recipe, we are going to take a look at how to use an e-mail action in order to notify users about job executions in Oozie.
Getting ready
To perform this recipe, you should have a running Hadoop cluster as well as the latest version of Oozie installed on it.
How to do it...
An 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 e-mail action:
<workflow-app xmlns="uri:oozie:workflow:0.2" name="pig-wf">
<start to="notify"/>
<action name="notify">
<email xmlns="uri:oozie:email-action:0.1">
<to>a@.b.com</to>
<cc>b@b.com</cc>
<subject>Email notifications for ${wf:id()}</subject>
<body>The wf ${wf:id()} successfully completed.</body>
</email>
<error to="fail"/>
</action>
<kill name="fail...
