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>[email protected]</to> <cc>[email protected]</cc> <subject>Email notifications for ${wf:id()}</subject> <body>The wf ${wf:id()} successfully completed.</body> </email> <error to="fail"/> </action> <kill name="fail...
