> From a long running cluster, we found tens of thousands of stale apps still be recovered in NM restart recovery.
> After investigating, there are three issues cause app state leak in NM state-store:
> 1. APPLICATION_LOG_HANDLING_FAILED is not handled with remove App in NMStateStore.
> 2. APPLICATION_LOG_HANDLING_FAILED event is missing in sent when hit aggregator's doAppLogAggregation() exception case.
> 3. Only Application in FINISHED status receiving APPLICATION_LOG_FINISHED has transition to remove app in NM state store. Application in other status - like APPLICATION_RESOURCES_CLEANUP will ignore the event and later forget to remove this app from NM state store even after app get finished.
