Running Multiple Instances of the Spark Operator

Running Multiple Instances of the Spark Operator within the Same K8s Cluster

If you need to run multiple instances of the Spark operator within the same k8s cluster, then you need to ensure that the running instances should not watch the same spark job namespace. For example, you can deploy two Spark operator instances in the spark-operator namespace, one with release name spark-operator-1 which watches the spark-1 namespace:

# Create the spark-1 namespace if it does not exist
kubectl create ns spark-1

# Install the Spark operator with release name spark-operator-1
helm install spark-operator-1 spark-operator/spark-operator \
    --namespace spark-operator \
    --create-namespace \
    --set 'spark.jobNamespaces={spark-1}'

And then deploy another one with release name spark-operator-2 which watches the spark-2 namespace:

# Create the spark-2 namespace if it does not exist
kubectl create ns spark-2

# Install the Spark operator with release name spark-operator-2
helm install spark-operator-2 spark-operator/spark-operator \
    --namespace spark-operator \
    --create-namespace \
    --set 'spark.jobNamespaces={spark-2}'
