Arun C Murthy updated MAPREDUCE-954:
------------------------------------
Attachment: MAPREDUCE-954.patch
Here is a nearly complete patch for illustrative purposes.
I've had to resort to composition in {Mapper|Reducer}Impl.Context to include a
member {Map|Reduce}ContextImpl to get around the fact that
{Mapper|Reducer}.Context is an abstract class, thus resulting in the inability
to get {Mapper|Reducer}Impl.Context to extend both {Mapper|Reducer}.Context
and {Map|Reduce}ContextImpl (MI).
> The new interface's Context objects should be interfaces

> When I was doing HADOOP-1230, I was persuaded to make the Context objects as
> classes. I think that was a serious mistake. It caused a lot of information
> leakage into the public classes.
