Customizing Spark Operator

To customize the operator, you can follow the steps below:

1. Compile Spark distribution with Kubernetes support as per Spark documentation.
2. Create docker images to be used for Spark with docker-image tool.
3. Create a new operator image based on the above image. You need to modify the FROM tag in the Dockerfile with your Spark image.
4. Build and push your operator image built above.
5. Deploy the new image by modifying the /manifest/spark-operator-install/spark-operator.yaml file and specifying your operator image.
