Wangda Tan commented on YARN-1885:
----------------------------------

[~jlowe], you're right. The old node will be replaced by new node in 
ReconnectNodeTransition. My bad, sorry for this.

> RM may not send the finished signal to some nodes where the application ran 
> after RM restarts

> During our HA testing we have seen cases where yarn application logs are not 
> available through the cli but i can look at AM logs through the UI. RM was 
> also being restarted in the background as the application was running.
