The Metron service includes all of the Metron pieces, so you should only really need one Metron service installed in one host. The actual work of Metron is one on the Storm supervisors, Solr servers, HDFS data nodes, Kafka brokers, and the YARN NodeManagers, so adding more of those workers depending on what you are scaling for is the way to scale it, you can then change the parallelism settings for your metron component (see the tuning guide in the docs) to make good use of your new hosts. The underlying platform (HDP) will be what allows you to scale.
