mapred.min.split.size and minimum map tasks properties of Hadoop MR also
control the splitting of input for map talks.

Outputs are not dependent on number of inputs, but instead the number of
reducers (if MapReduce) or number of input splits if just plain Maps.

The number of splits is determined in most cases by the input file sizes and
the set HDFS block size factor (dfs.block.size) it was created under.
