-On enabling Dynamic allocation, Executors scale up or down based on the utilization of the Executors. This ensure that the Executors are provisioned in accordance with the needs of the job being run.
+In this example, if your job requires only 2 executors, it will use only 2 executors.  When the job requires more, it will scale up to 6 executors (1 driver, 6 executors).  When the job doesn't need the executors, then it will decommission the executors. If it doesn't need the node, it will free up the node.
