 Then the chart will set up a service account for your Spark jobs to use in that namespace.

 ## About Spark Job Namespaces
 
-The Spark Job Namespaces value defines the namespaces where `SparkApplications` can be deployed. The Helm chart value for the Spark Job Namespaces is `sparkJobNamespaces`, and its default value is `[]`. When the list of namespaces is empty the Helm chart will create a service account in the namespace where the spark-operator is deployed.

 The Spark Operator uses the Spark Job Namespace to identify and filter relevant events for the `SparkApplication` CRD. If you specify a namespace for Spark Jobs, and then submit a SparkApplication resource to another namespace, the Spark Operator will filter out the event, and the resource will not get deployed. If you don't specify a namespace, the Spark Operator will see only `SparkApplication` events for the Spark Operator namespace.
