Mahadev konar commented on MAPREDUCE-3832:
------------------------------------------
@Alejandro,
I am not sure I get the issue here. How does it affect backwards/forward
compatibility?
> mapred Counters API should not extend mapreduce Counters API
> ------------------------------------------------------------
>
> Key: MAPREDUCE-3832
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3832
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.1
> Reporter: Alejandro Abdelnur
> Priority: Critical
>
> The mapred (old) Counters API extends the mapreduce (new) Counters API, this
> effectively makes the old Counters API dependent on the new Counters API.
> This may affect stability and backwards/forward compatibility in the old
> Counters API.
> The new API should not pop up as dependency in the old API. Instead it should
> only be used in the implementation when necessary.
