Chris Douglas commented on MAPREDUCE-2492:
------------------------------------------
This is partially my fault. I only had time for a quick pass over the patch,
and had missed the mapred API change among the updates to {{mapreduce.lib}}
classes.
I agree with Tom. It's a useful feature, but changing only the new API is
probably the better course. Any breakage is unlikely- it's adding, not removing
a method from a framework type almost never implemented by users- but I'd lean
away from any modifications to the old APIs unless they affect correctness.

> There is no way to get the task's current progress in the new MapReduce API.
> It would be nice to make it available so that the task (map/reduce) can use
> it.
