--------------------------------------
Summary: 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.
