> Set "reuse address" flag on listen sockets
> ------------------------------------------
>
> Key: SPARK-24029
> URL: https://issues.apache.org/jira/browse/SPARK-24029
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.4.0
> Reporter: Marcelo Vanzin

>
> 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.
