Wangda Tan commented on YARN-10504:
-----------------------------------

Thanks [~zhuqi], [~bteke] and review from [~sunilg].  

I suggest let's go ahead with ver.010, and deal with the abs resource in a 
follow-up Jira. This Jira is already very large and we need more clean up for 
the absolute resource + weight + percent rather than just fixing the problem 
itself. Also, this Jira blocked a number of efforts such as YARN-10506. 

Thoughts?

> To allow the possibility to flexibly create queues in Capacity Scheduler a 
> weight mode should be introduced. The existing \{{capacity }}property should 
> be used with a different syntax, i.e:
> root.users.capacity = (1.0) or ~1.0 or ^1.0 or @1.0
> root.users.capacity = 1.0w
> root.users.capacity = w:1.0
> Weight support should not impact the existing functionality.
>  
> The new functionality should: 
>  * accept and validate the new weight values
>  * enforce a singular mode on the whole queue tree
>  * (re)calculate the relative (percentage-based) capacities based on the 
> weights during launch and every time the queue structure changes
