Vinod Kumar Vavilapalli commented on YARN-2074:

[~sunilg], Agree that as much as possible we should avoid killing the AM during 
preemption and so we should look at YARN-2022 orthogonally. This one focuses 
only on the point that in the case that this cannot be avoided, it shouldn't be 
accounted towards AM failures.

> One orthogonal concern with issues like YARN-2055 and YARN-2022 is that AM 
> containers getting preempted shouldn't count towards AM failures and thus 
> shouldn't eventually fail applications.
> We should explicitly handle AM container preemption/kill as a separate issue 
> and not count it towards the limit on AM failures.
