Sunil G commented on YARN-7806:
-------------------------------

Patch looks straight forward to me. All the other timeline apis are async 
already, hence making async will avoid such timeout cases. +1

> DS will hang if ATSv2 back end is unavailable.

> DS publishes container start/stop events using sync API. If back end is  down 
> for some reasons, then DS will hang till container start/stop events are 
> published. By default, retry is 30 and interval is 1sec.
> To publish single entity using sync API will take 1 minutes to come out. In 
> case of DS, if number of containers are 10 then 10minutes for start event and 
> 10minutes for stop event. Overall 20 minutes will wait.
>  
> DS should publish container events using asyn api.
