Yes, this is know issue and a bug has been opened to fix/improve upon this https://issues.apache.org/jira/browse/HADOOP-2302 For now, you could emit your keys as 01, 02 instead of 1, 2 which will sort the keys in numerical order. Thanks, Lohit

It seems that the sorted values are based on dictionary, for eg: 1 12 15 2 28 What if I want to get numerical sorted list: 1 2 12 15 28 What partitioner shall I use?
