Recently I took the certification exam and this was the question.
With the Block size set to 128MB and two files each with 10 GB and 256MB, how many mappers will run?
Can somebody explain in detail why 82 or 84 was not an option among the answers?

Not sure about that part, because it has been a while now.
Can you explain the factors which affect the mapper count and how the number of mappers is decided, ( i know it is based on input splits) please
Thank you in advance
