Scheduling a job in Oozie

In this recipe, we are going to take a look at a schedule that has recurring jobs using the Oozie coordinator.

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...

Oozie provides one more type of job called a coordinator job. This type of job is used to schedule application jobs. With the help of a coordinator job, we can execute an application job. The following is an example of a coordinator job that runs daily:

<coordinator-app name="sample-coordinator"
  frequency="${coord:days(1)}"
  start="2016-01-01T18:56Z" end="2017-01-01T18:56Z" timezone="UTC"
  xmlns="uri:oozie:coordinator:0.2">

<controls>

<concurrency>1</concurrency>
<execution>FIFO</execution>
<throttle>5</throttle>
</controls>


<action>
<workflow>
<app-path>${applicationPath}</app-path>
<configuration>
       ...
</configuration...
