[jira] [Created] (MAPREDUCE-3832) mapred Counters API should not extend mapreduce Counters API

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.
