[jira] [Commented] (YARN-10504) Implement weight mode in Capacity
Scheduler
[ https://issues.apache.org/jira/browse/YARN-10504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17241118#comment-17241118 ]

-----------------------------------
[~bteke], does the Queue Priorities feature (YARN-5864) meet your requirements?
> Implement weight mode in Capacity Scheduler
> -------------------------------------------
>
> Key: YARN-10504
> URL: https://issues.apache.org/jira/browse/YARN-10504
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Benjamin Teke
> Assignee: Benjamin Teke
> Priority: Major
>
> 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
