For this reason you shouldn't use the master node of your cluster as your driver machine. Many organizations submit Spark jobs from what's called an edge node, which is a separate machine that isn't used to store data or perform computation. Since the edge node is separate from the cluster, it can go down without affecting the rest of the cluster.
