------------------------------------------
@Alejandro,
I have a similar patch which tries to do something like this but I am running
into some issues with it when I do the same thing with Group. Looks like some
issue where the write fields doesnt match the readfields for TaskStatus (where
Counters are used) and the tasks hang. Am still debugging that. After doing
this for a couple of days, I am actually not averse to copying over the code to
mapred.Counters :).

> Oozie uses Hadoop Counters API, by invoking Counters.getGroup(). However, in
> hadoop 23, org.apache.hadoop.mapred.Counters does not implement getGroup().
> Its
> parent class AbstractCounters implements it. This is different from hadoop20X.
> As a result, Oozie compiled with either hadoop version does not work with the
> other version.
> A specific scenario, Oozie compiled with .23 and run against 205, does not
> update job status owing to a Counters API exception.
> Will explicit re-compilation against the relevant hadoop jars be required each
> time? This will prevent launching a uniform Oozie version across different
> clusters.
