I understand what input split size and what a block size means. But what I am trying to understand is where and how the input split size is mentioned for a MR program... is it passed a parameter while starting a MR job using (Hadoop jar MRPROGRAM ... etc) or is it specified in the MR Job configuration program or is it mentioned some where else. Please explain.
How and where is input split size mentioned or passed to a MR program?
