Zhijie Shen commented on YARN-3039:
-----------------------------------

Thanks for your input, [~jianhe]! Given it may needs more treatment for state 
preserving, shall we spin off the related code change and defer it to a later 
jira? I think it shouldn't block out next milestone.

> Per design in YARN-2928, implement ATS writer service discovery. This is 
> essential for off-node clients to send writes to the right ATS writer. This 
> should also handle the case of AM failures.
