Is there any relation between the Context (via getContext()) in a Mapper vs the Context found in a corresponding Reducer (via getContext)?  

I'm wondering if I track a counter in a Mapper if I'll have access to it in the Reducer, or if that's a totally separate "context".  Seems like they should be totally separate since the Context class has other methods like #getShardCount, etc, but just wanted to clarify.

Thanks,
david

The context objects are separate.
