Amareshwari Sriramadasu updated MAPREDUCE-372:
----------------------------------------------
Attachment: patch-372.txt
Attaching patch for review.
Patch implements ChainMapper and ChainReducer as proposed by Owen.
The key and values are always passed *by value* from one element of the chain
to the next, because we
clone the keys and values between steps. This removes the option to pass by
value or by reference, that was available in old api.
> Change org.apache.hadoop.mapred.lib.ChainMapper/Reducer to use new api.
