https://github.com/apache/spark/pull/9076
Update DAGScheduler's "misbehaved ResultHandler"
Restrict tasks (of job) to only 1 to ensure that the causing Exception
asserted for job failure is the deliberately thrown
DAGSchedulerSuiteDummyException intended, not an UnsupportedOperationException
from any second/subsequent tasks that can propagate from a race condition
during code execution.
