Re: get different results when debugging and running scala program
The question has no connection to spark.
In future, if you use apache mailing lists, use external services to add

Re: get different results when debugging and running scala program
There is no image attached, I'm not sure how the apache mailing lists
handle them. Can you provide the output as text?
