Marcelo Vanzin 767d288b6b [SPARK-11655][CORE] Fix deadlock in handling of launcher stop(). ... The stop() callback was trying to close the launcher connection in the same thread that handles connection data, which ended up causing a deadlock. So avoid that by dispatching the stop() request in its own thread. On top of that, add some exception safety to a few parts of the code, and use "destroyForcibly" from Java 8 if it's available, to force kill the child process. The flip side is that "kill()" may not actually work if running Java 7. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #9633 from vanzin/SPARK-11655.		2015-11-12 14:29:16 -08:00
