------------------------------------
Attachment: MAPREDUCE-954.patch
Here is an updated patch which shows the plan to use the new org.apache.hadoop.mapreduce.lib.{map|reduce}.Wrapped{Mapper|Reducer}
to completely get away from the ugly hacks for mrunit, Chain{Mapper|Reducer} etc.
> The new interface's Context objects should be interfaces
