While the parameters for the enrichments topology should be modified via Ambari for persistence, you can start the topologies via the command line on the Metron node and easily modify parameters for testing. The commands below demonstrate how to create a copy of the Metron files for making changes quickly during testing.

  1. From the user’s home directory, execute the following commands:
    sudo cp /usr/hcp/current/metron/bin/start_enrichment_topology.sh ~
      sudo cp /usr/hcp/current/metron/config/enrichment.properties ~
      sed -i 's+$METRON_HOME/config/+/home/<user>/+g' ./start_enrichment_topology.sh
  2. Edit the variables:
    vi ~/enrichment.properties
  3. To start the topology with the new variables, execute the following command:
