> a few problems:
> - if a job is retired - then counters cannot be obtained and a stack trace is printed
out (from history code). this confuses users
> - too many calls to getCounters. after a job has been detected to be finished - there
are quite a few more calls to get the job status and the counters. we need to figure out a
way to curtail this - in busy clusters the gap between the job getting finished and the hive
client noticing is very perceptible and impacts user experience.
> calls to getCounters are very expensive in 0.20 as they grab a jobtracker global lock
(something we have fixed internally at FB)
