Benjamin Teke commented on YARN-10504:
--------------------------------------
Hey [~zhuqi],
Thanks for your updates. Took the liberty to refactor/include your changes in
my latest patch. Also based on our offline discussion with [~gandras] I removed
some parts of his 002 patch, as it will be handled differently. As you have
mentioned the AutoQueueCreation should now work, because the leafQueueTemplates
should now have the correct absolute capacities. I will now turn to the
AbsoluteResourceWithAutoQueue issue and handle the maxApplications in auto
created cases.
If you upload a new patch please use the 005 patch as base, because that
contains the latest from our side and also includes your changes from 003/004
patch.
Thanks!

> 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
