Trapezium is a maven project. Following instructions will create Trapezium jar for your repository. On all your Spark nodes, create a file /opt/bda/environment and add environment for your cluster, e.g., DEV|QA|UAT|PROD. You can do this through a setup script so that any new node to your cluster will have this file automatically created. This file allows Trapezium to read data from different data sources or data locations based on your environment.
