Hello, I implemented a very simple custom WritableComparable which works fine as is but I wanted to improve performance by implementing the appropriate WritableComparator as well. The comparator does not seem to work as keys which really should be the same are different according to the reduce method.
I uploaded the code here: http://pastebin.com/usykcA1r Any ideas where I am going wrong in my code? Again, if I comment the WritableComparator everything works as expected. Thanks a lot, /David I followed the guidelines here: http://developer.yahoo.com/hadoop/tutorial/module5.html#writable-comparatorand also Chapter 4, page 106 o'Reilly Hadoop Book 3rd edition
