> Hadoop Counters API limits Oozie's working across different hadoop versions
> ---------------------------------------------------------------------------

> Key: MAPREDUCE-3697
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3697
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.1
> Reporter: John George
> Assignee: Mahadev konar

>
> 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.
