The critical item is that your map's output key should be IntWritable
instead of Text. The default comparator for IntWritable will give you
properly sorted numbers. If you stringify the numbers and output them
as text, they'll get sorted as strings.

Hi,
I am trying to sort a list of numbers (one per line) using hadoop
mapreduce.
Kindly suggest any reference and code.
How do I implement custom input format and recordreader so that both key and
value are the number?
I am using Hadoop 0.20.2
Thanks
Neil
