This scenario applies only to Talend Real-time Big Data Platform or Talend Data Fabric.

In this scenario, a four-component Storm Job (a topology) is created to transmit
messages about the activities of some given people to the topology you are designing in
order to analyze the popularities of those activities.

This Job subscribes to the related topic created by the Kafka topic producer, which means
you need to install the Kafka cluster in your messagingg system to maintain the feeds of
messages. For further information about the Kafka messaging service, see Apache’s
documentation about Kafka.

On the other hand, since this Job runs on top of Storm, you need to ensure that your Storm
system is ready for use. For further information about Storm, see Apache’s documentation
about Storm.

Note that when you use the Storm system installed in the Hortonwork Data Platform 2.1
(HDP2.1), ensure that the Storm DRPC (distributed remote procedure call) servers’ names
have been properly defined in the Custom storm.yaml section of the Config tab of Storm
in Ambari’s web console. For example, you need to use two Storm DRPC servers which are
Server1 and Server2, then you must define them in the Custom storm.yaml secton as
follows: [Server1,Server2].

To replicate this scenario, proceed as follows.
