Subject Is it possible to sort values before they are sent to the reduce function?
Date Mon, 14 Jun 2010 02:16:59 GMT
Hi,
For each key, there might be millions of values(LongWritable), but I only
want to emit top 20 of these values which I want to be sorted in descending
order.
So is it possible to sort these values before they enter the reduce phase?

Thank you in advance!
Kevin
