> The following very simple MapReduce program reads data from one table which
> it assumes to have an integer in the second column, and counts how many
> different values it sees. That is, it does the equivalent of "select col1,
> count(*) from $table group by col1;".
> The description of the query is wrong. It actually counts how many instances
> of each distinct value it find. For example, if values of col1 are
> {1,1,1,3,3,3,5) it will produce
> 1, 3
> 3, 2,
> 5, 1
