Aaron Kimball commented on MAPREDUCE-1920:
------------------------------------------
The new API seems to have an issue w.r.t. counters. Calling Job.getCounters()
after the job has completed (successfully) returns null. I can see all the
counters there on the JobTracker status web page. They have the correct values.
But I can't access them programmatically.
So, this is returning null:
{code}
public class Job extends JobContextImpl implements JobContext {
...
public Counters getCounters()
throws IOException, InterruptedException {
ensureState(JobState.RUNNING);
return cluster.getClient().getJobCounters(getJobID());
}
}
{code}
This seems to work fine with the LocalJobRunner.
