To try this yourself on a Kubernetes cluster, simply download the binaries for the official [Apache Spark 2.3 release][13]. For example, below, we describe running a simple Spark application to compute the mathematical constant Pi across three Spark executors, each running in a separate pod. Please note that this requires a cluster running Kubernetes 1.7 or above, a [kubectl][14] client that is configured to access it, and the necessary [RBAC rules][9] for the default namespace and service account.
