Assuming you cloned this repo into location SONAR_DRIVER_HOME

1-step install: source install.sourceme

Or, build components separately using:

1. Run make to create the necessary python virtualenv for this project and pip install it into the virtualenv.

2. Invoke the virtual environment with source ${SONAR_DRIVER_HOME}/venv/bin/activate

3. Add ${SONAR_DRIVER_HOME}/bin to PATH to run commands anywhere

The following environment variables may be used by the commands in bin if set:

KAFKA_REST_URL      # e.g. http://sonar8
KAFKA_REST_PORT     # e.g. 8083
CQLSH_HOST          # e.g. sonar8
CQLSH_PORT          # e.g. 9042
ZOOKEEPER_HOST      # e.g. sonar8
ZOOKEEPER_PORT      # e.g. 2181
