Please change documentation:
helm install my-release spark-operator/spark-operator
--namespace spark-operator
--create-namespace
--set "sparkJobNamespaces={spark}"
--set webhook.enable=true
--set webhook.port=443

TO:
helm install my-release spark-operator/spark-operator
--namespace spark-operator
--create-namespace
--set "spark.jobNamespaces={spark}"
--set webhook.enable=true
--set webhook.port=443

Change: It needs to be "spark.jobNamespaces" NOT sparkJobNamespaces - I spent lot of time to finally figure this out :) So it might save time for others
