> We propagate exceptions from Spark task failures to the client well, but we don't differentiate
between errors from HS2 / RSC vs. errors thrown by individual tasks.
> Main motivation is that when the client sees a propagated Spark exception its difficult
to know what part of the excution threw the exception.
