> Found this while reviewing YARN-3480.
> bq. When 'attemptFailuresValidityInterval'(introduced in YARN-611) is set to 
> a small value, retried attempts might be very large. So we need to delete 
> some attempts stored in RMStateStore and RMStateStore.
> I think we need to have a lower limit on the failure-validaty interval to 
> avoid situations like this.
> Having this will avoid pardoning too-many failures in too-short a duration.
