Wangda Tan commented on YUNIKORN-317:
-------------------------------------

Had a brief discussion with [~cheersyang] and [~wilfreds], we agree the two 
modules together is a good idea. 

Since it will involve lots of changes, before making changes, we need to better 
design and plan. I'm writing a design/analysis doc for the proposal. (Design 
doc/analysis will follow).

> [CORE] Cache/Scheduler modules need to be combined to a single module

>                 URL: https://issues.apache.org/jira/browse/YUNIKORN-317
>             Project: Apache YuniKorn
>          Issue Type: Improvement
>          Components: core - cache, core - scheduler
>            Reporter: Wangda Tan
>            Priority: Major
>
> Now we have two modules inside core:
>  * Cache
>  * Scheduler
> Between Cache and Scheduler, they communicate with each other using async 
> events, which causes lots of inconsistent issues. (Such as YUNIKORN-169). 
> Also, it complex logic a lot, there're 10 out of 19 events are only between 
> cache and scheduler.
