* SPARK-24294: To bypass scala bug: https://github.com/scala/bug/issues/9554, we catch
* fatal throwable in {@link scala.concurrent.Future}'s body, and re-throw
* SparkFatalException, which wraps the fatal throwable inside.
* Note that SparkFatalException should only be thrown from a {@link scala.concurrent.Future},
* which is run by using ThreadUtils.awaitResult. ThreadUtils.awaitResult will catch
* it and re-throw the original exception/error.
