Robert Kanter commented on MAPREDUCE-5856:
------------------------------------------
The problem is that Limits is looking for the mapred-site.xml in the classpath,
or failing that, the defaults. This is a problem for clients such as Oozie
where we don't have mapred-site.xml on the classpath, and instead create a
JobClient by passing it a Configuration object to use instead (where the
counters limit is increased).
> Counter limits always use defaults even if JobClient is given a different
> Configuration

> If you have a job with more than the default number of counters (i.e. > 120),
> and you create a JobClient with a Configuration where the default is
> increased (e.g. 500), then JobClient will throw this Exception:
> {noformat}
> org.apache.hadoop.mapreduce.counters.LimitExceededException: Too many
> counters: 121 max=120
> {noformat}
