Counters group names deprecation is wrong, iterating over group names deprecated names don't show up
----------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-4053
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4053
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.24.0, 0.23.3
            Reporter: Alejandro Abdelnur
            Priority: Critical
             Fix For: 0.23.3


This is similar to the deprecation of Configuration properties bug HADOOP-8167, interator() retrieval of counter names only returns new names.

Oozie breaks here because it is using the deprecate name and iterating over values (OOZIE-777). While it can be worked around easily in Oozie, this is breaking backwards compatibility.
