Hello:

I wrote a simple Map/Reduce program. The ouput key of the Map function is a 
user defined datum(class)
with two member strings. The OutputKeyComparatorClass is set to this datum 
class and the class 
implements the "compareTo" function. 

The problem is the final MapOutput from reduce has the same "key" occuring in 
more than one record.
Any thougts on why this could happen?

Also I see that the compareTo function never gets as input the pair of "keys" 
that are same for comparison.....

Regards,
Ilay
