> Currently, if any abnormal happens in ZKRMStateStore, it will throw a fetal exception to crash RM down. As shown in YARN-1924, it could due to RM HA internal bug itself, but not fatal exception. We should retrospect some decision here as HA feature is designed to protect key component but not disturb it.
