Description

Commit https://github.com/apache/spark/commit/1c9a386c6b6812a3931f3fb0004249894a01f657 changed the behavior of driver process termination. Whereas before `Process.destroyForcibly` was never called, now it is called (on Java VM's supporting that API) if the driver process does not die within 10 seconds.

This prevents apps which take longer than 10 seconds to shutdown gracefully from shutting down gracefully. For example, streaming apps with a large batch duration (say, 30 seconds+) can take minutes to shutdown.
