I need help. No matter what I do I can't seem to get Hadoop to find my custom partitioner. Here is the command I am running:
../bin/hadoop jar ../contrib/streaming/hadoop-streaming-1.2.1.jar \ -libjars ./NumericPartitioner.jar \ -input /input -output /output/keys -mapper "map_threeJoin.py" -reducer "keycount.py" \ -partitioner newjoin.NumericPartitioner -file "map_threeJoin.py" -file "keycount.py" (The code of NumericPartitioner is very simple, and is here: http://pastebin.com/ZEK7N1RN) But no matter what I do, it gives: -partitioner : class not found : newjoin.NumericPartitioner Does anyone have any idea why it might be going wrong?
