Sangjin Lee commented on YARN-4343:
-----------------------------------

So if I understood correctly, what we're discussing here is to support YARN CLI 
support for handling YARN-generic app information coming from the timeline 
service storage, correct? We're *NOT* envisioning a separate notion of AHS 
here, correct?

I'm in agreement that we should see if we can do it on top of the REST API.

Could you come up with a simple proposal of what needs to be done and share it? 
I think that will help us moving forward the discussion. Thanks!

> AHS is used by the CLI and Webproxy(REST), if the application related 
> information is not found in RM then it tries to fetch from AHS and show
