There is an issue in general with setting a driver
SparkUncaughtExceptionHandler as described in here:
[https://github.com/apache/spark/pull/24796]. I am also in favor of a handler,
where we can just sys.exit without running any shutdown hook logic though
because of the deadlock issue.

so we need to do the same. The upgrade happened because the client was very old.
