Not clear what you mean here. A Spark program is a program, so what are the alternatives here? program execution order is still program execution order. You are not guaranteed anything about order of concurrent tasks. Failed tasks can be reexecuted so should be idempotent. I think the answer is 'no' but not sure what you are thinking of here.
