[~hex108], i know it's been a long time, would you still like to work on this  ?
IMO, as a first step, we can do as in previous

 to remove the apps beyond the validity interval as mostly those apps user care 
least. cc [~xgong]. 

> Recovery may get very slow with lots of services with lots of app-attempts

> When RM HA is enabled and running containers are kept across attempts, apps 
> are more likely to finish successfully with more retries(attempts), so it 
> will be better to set 'yarn.resourcemanager.am.max-attempts' larger. However 
> it will make RMStateStore(FileSystem/HDFS/ZK) store more attempts, and make 
> RM recover process much slower. It might be better to set max attempts to be 
> stored in RMStateStore.
> BTW: 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.
