Hello, I want to know more details on using Hadoop framework to sort input data. In example, sorting can be as simple as using identical map and reduce class, and just allow the framework to do its basic work. >From article http://hadoop.apache.org/core/docs/r0.19.1/mapred_tutorial.html#Overview, I learned that a number of classes, such as comparator and partitioner, can be involved in the process, but I can not find more details how it takes place. Could someone help? Thanks.
-- Cheers! Hadoop core
