> From the logs, it seems the ipc retry interval is set as 20 seconds and ipc 
> max retries is 45. This means that the client will retry the RPC connection 
> for total 900 (20*45) seconds. And in this period, the application may 
> already complete and RM Restarting may be triggered as said in the jira 
> description. And I think the RM recovery is not enabled, so even the new RM 
> is restarted, the original application info is lost, that means the client 
> can never get the correct application report which makes it showing the old 
> status forever.

> Configuration to reproduce this issue
> * disable generic application history 
> (yarn.timeline-service.generic-application-history.enabled)
> * disable rm recovery (yarn.resourcemanager.recovery.enabled)
> * increase the ipc retry interval and max retry 
> (ipc.client.connect.retry.interval & ipc.client.connect.max.retries)
