Benjamin Teke commented on YARN-10504:
--------------------------------------
Sharing my latest findings on TestAbsoluteResourceWithAutoQueue failure:
{{AutoCreatedLeafQueue#reinitializeFromTemplate }}was refactored, now the
getting and merging the QueueCapacities happens *before* calling the
{{ParentQueue#updateClusterResource}} (and
{{LeafQueue#updateClusterResource}}). In {{LeafQueue#updateClusterResource
}}the {{AbstractCSQueue#updateEffectiveResources }}is called where the
effectiveMinResource of the created queue is overridden with the template's
effectiveMinResources which is exactly the same the test is getting in the
asserts.
{code:java}
void updateEffectiveResources(Resource clusterResource) {
Set<String> configuredNodelabels =
csContext.getConfiguration().getConfiguredNodeLabels(getQueuePath());
for (String label : configuredNodelabels) {
Resource resourceByLabel = labelManager.getResourceByLabel(label,
clusterResource); Resource minResource =
queueResourceQuotas.getConfiguredMinResource(
label); // Update effective resource (min/max) to each child
queue.
if (getCapacityConfigType().equals(
CapacityConfigType.ABSOLUTE_RESOURCE)) {
queueResourceQuotas.setEffectiveMinResource(label,
getMinResourceNormalized(queuePath,
((ParentQueue) parent).getEffectiveMinRatioPerResource(),
minResource));
...{code}

> 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
