Running Oozie MapReduce job

Oozie has a command-line functionality to submit a job, which has just a MapReduce action. The command-line option that we saw in the previous action can be used anywhere when we have a Workflow or Coordinator with complex DAG.

To run Oozie job, which is just a simple MapReduce, we can use the command options shown in the following screenshot:

Oozie MapReduce command line

Here's an example:

oozie mapreduce -config job.properties -oozie http://localhost:11000/oozie

Tip

We can also choose to pass on variables such as input and output from the command line.

In this section, we made our Workflow using the MapReduce action and used the command-line Oozie job option with the job.properties file to run the same.

Let's move on to the next topic of Coordinators.
