Managing your Apache Spark service
You can set up an Apache Spark service when you create a project or anytime from the Settings page in a project.
The Spark service runs up to 10 kernels. Each notebook runs on a dedicated kernel. You can stop kernels on the Actions list for the notebook in your project.
If you have Watson Studio Enterprise, see Set up Watson Studio Enterprise account.
If you have more than one Spark service, you can change the Spark service that is associated with a project. Go to the Settings screen of the project page. In the Associate Services section, you can remove the existing Spark service and add a new one.
