Wangda Tan commented on YARN-10504:
-----------------------------------
1) AbstractCSQueue, lots of format changes, can we revert all format change
(change spaces). Since it will cause issues when backport and reviews
2) LeafQueue:
There're two TODOs:
//TODO recalculate max applications because they can depend on capacity
//TODO recalculate max applications because they can depend on capacity
I think it took care by the {{updateAbsoluteCapacitiesAndRelatedFields}},
please double check, and if it is correct, we should remove the TODOs
3) TestAbsoluteResourceWithAutoQueue:
I added a TODO:
TODO: Wangda: I think this test case is not correct, Sunil could help look
// into details.
4) TestCapacitySchedulerAutoCreatedQueueBase.java
I also added a TODO
// TODO: Wangda, I think this is a wrong test, it doesn't consider rounding
...
[~bteke], [~gandras], [~zhuqi] if any of you plan to make change to the patch,
please add a comment to the JIRA so others will know, otherwise the patch will
be hard to merge.

> 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
