      Description

      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.
