> Pipes is still currently using the old mapred API. This prevents us from 
> using pipes with HBase's TableInputFormat, HRegionPartitioner, etc. 
> Here is a rough proposal for how to accomplish this:
> * Add a new package org.apache.hadoop.mapreduce.pipes that uses the new 
> mapred API.
> * the new pipes package will run side by side with the old one. old one 
> should get deprecated at some point.
> * the wire protocol used between PipesMapper and PipesReducer and C++ 
> programs must not change.
> * bin/hadoop should support both pipes (old api) and pipes2 (new api)
> Does this sound reasonable?
