> 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.
