yantzu commented on issue #223: [LIVY-658]RSCDriver should catch exception if cancel job failed
during shutdown

   Without catch cancel exception, the original exception("scala.refrect.internal.FactalError:
object Predef does not have a member classOf" in the screen-shoot) is concealed by NullPointerException,
it is not easy to find application error root cause(which is FactalError in this case). @runzhiwang
