The job will consume a feed of real-time edits from Wikipedia, and produce them to a Kafka topic called "wikipedia-raw". Give the job a minute to startup, and then tail the Kafka topic:

{% highlight bash %}
deploy/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic wikipedia-raw
deploy/kafka/bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic wikipedia-raw
{% endhighlight %}

Pretty neat, right? Now, check out the YARN UI again ([http://localhost:8088](http://localhost:8088)). This time around, you'll see your Samza job is running!

The first job (wikipedia-parser) parses the messages in wikipedia-raw, and extracts information about the size of the edit, who made the change, etc. You can take a look at its output with:

{% highlight bash %}
deploy/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic wikipedia-edits
deploy/kafka/bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic wikipedia-edits
{% endhighlight %}

The last job (wikipedia-stats) reads messages from the wikipedia-edits topic, and calculates counts, every ten seconds, for all edits that were made during that window. It outputs these counts to the wikipedia-stats topic.

{% highlight bash %}
deploy/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic wikipedia-stats
deploy/kafka/bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic wikipedia-stats
{% endhighlight %}

The messages in the stats topic look like this:
