> Setting the "reuse address" option allows a server socket to be bound to a port that may still have connections in the "close wait" state. Without it, for example, re-starting the history server could result in a BindException.
> This is more important for things that have explicit ports, but doesn't hurt also in other places, especially since Spark allows most servers to bind to a port range by setting the root port + the retry count.
