The Docker image dclong/jupyterhub-toree has Spark and Apache Toree installed and configured. Since Spark is already installed in it, you don't need to download and install Spark by yourself. By default, a Spark Session object named spark is created automatically just like spark-shell. So, you can use Spark/Scala out-of-box in a JupyterLab notebook with the Scala - Apache Toree kernel.

1. Open a JupyterLab notebook with the Scala - Apache Toree kernel from the launcher.

2. Use Spark as usual.
