Naganarasimha G R commented on YARN-4700:
-----------------------------------------

It might be mostly the case of asynchronous or, its not necessary that ATS is 
running initially but starts up after RM failsover. 
But in any case would not better to link up with asynchronous and synchronous 
events for V2.

> ATS storage has one extra record each time the RM got restarted

> When testing the new web UI for ATS v2, I noticed that we're creating one 
> extra record for each finished application (but still hold in the RM state 
> store) each time the RM got restarted. It's quite possible that we add the 
> cluster start timestamp into the default cluster id, thus each time we're 
> creating a new record for one application (cluster id is a part of the row 
> key). We need to fix this behavior, probably by having a better default 
> cluster id.
