------------------------------------------------------------

Thanks for verifying [~giovanni.fumarola]. Was just looking closely again.
In {{submitApplication}} method for eg,
we have a loop for number of retries, and you do 
{{routerMetrics.incrAppsFailedSubmitted()}} everytime it fails in the loop. 
Shouldn't that metric be incremented only if submit has failed for ALL the 
retires ?
I see the same pattern in all the calls. If that is the expected behavior, I am 
fine with it, but just confirm if that is in fact the expected behavior.
