> org.apache.spark.util.ShutdownHookManager is used to register custom shutdown
> operations. This is not easily configurable. The underlying
> org.apache.hadoop.util.ShutdownHookManager has a default timeout of 30
> seconds. It can be configured by setting hadoop.service.shutdown.timeout,
> but this must be done in the core-site.xml/core-default.xml because a new
> hadoop conf object is created and there is no opportunity to modify it.
> org.apache.hadoop.util.ShutdownHookManager provides an overload to pass a
> custom timeout. Spark should use that and allow a user defined timeout to be
> used.
> This is useful because we see timeouts during shutdown and want to give some
> extra time for the event queues to drain to avoid log data loss.
