While the parameters for the Enrichments topology should be modified via Ambari for
persistence, there is a method by which the topologies can be started via the command line on
the Metron node and parameters easily modified for testing. The commands below demonstrate how
to create a copy of the Metron files for making changes quickly during testing.
-
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
-
Now, the variables can be edited outside of Ambari via the following command:
vi ~/enrichment.properties
-
To start the topology with the new variables, you must execute the following
command:
~/start_enrichment_topology.sh
