reads

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
