+This is an example DAG which uses SparkKubernetesOperator and SparkKubernetesSensor.
+In this example, we create two tasks which execute sequentially.
+The first task is to submit sparkApplication on Kubernetes cluster(the example uses spark-pi application).
+and the second task is to check the final state of the sparkApplication that submitted in the first state.
+
+Spark-on-k8s operator is required to be already installed on Kubernetes
