-reducer gets values with empty attributes
alxsss@... 2013-04-29, 20:59
I try to write mapreduce program in hadoop -1.0.4. using mapred libs. I have a map function which gets
keys and creates a different object with a few attributes like id and etc and passes it to reducer function using
Reducer gets keys, but values has empty fields (like id and etc) , although map correctly assigns these fields to each value.
Any ideas why this happens?
