From the post:
In our previous article [Introduction to Oozie] we described Oozie workflow server and presented an example of a very simple workflow. We also described deployment and configuration of workflow for Oozie and tools for starting, stoping and monitoring Oozie workflows.
In this article we will describe a more complex Oozie example, which will allow us to discuss more Oozie features and demonstrate how to use them.
