> Under heavy load circumstances on some Hadoop versions, we may get a NPE from
> trying to dereference a null Counters object. I don't have a unit test which
> can reproduce it, but here's an example stack from a production cluster we
> saw today:
> 10/06/21 13:01:10 ERROR exec.ExecDriver: Ended Job = job_201005200457_701060
> with exception 'java.lang.NullPointerException(null)'
