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.
