Srimanth Gunturi commented on YARN-1166:
----------------------------------------
Isnt the fix as simple as changing {{appsFailed}} type to
{{MutableCounterInt}}, and removing the below?
{code}
else {
appsFailed.decr();
}
{code}
This would make appsFailed cumulative, as in {{finishApp(AppSchedulingInfo,
RMAppAttemptState)}} we do the {{appsFailed.incr()}} on the final attempt state?
> YARN 'appsFailed' metric should be of type 'counter'

> Currently in YARN's queue metrics, the cumulative metric 'appsFailed' is of
> type 'guage' - which means the exact value will be reported.
> All other cumulative queue metrics (AppsSubmitted, AppsCompleted, AppsKilled)
> are all of type 'counter' - meaning Ganglia will use slope to provide deltas
> between time-points.
> To be consistent, AppsFailed metric should also be of type 'counter'.
