[jira] [Commented] (YARN-11006) Allow overriding user limit factor and maxAMResourcePercent with AQCv2 templates

---------------------------------------
Hi [~bteke],
Just committed your patch to trunk.
Could you please check whether it's required to backport this to branch-3.3 / branch-3.2?
Thanks.

> [YARN-10801|https://issues.apache.org/jira/browse/YARN-10801] fixed the template configurations for every queue property, but it introduced a strange behaviour as well. When setting the template configurations LeafQueue.setDynamicQueueProperties is called:
> {code:java}
> @Override
> protected void setDynamicQueueProperties(
> CapacitySchedulerConfiguration configuration) {
> super.setDynamicQueueProperties(configuration);
> // set to -1, to disable it
> configuration.setUserLimitFactor(getQueuePath(), -1);
> // Set Max AM percentage to a higher value
> configuration.setMaximumApplicationMasterResourcePerQueuePercent(
> getQueuePath(), 1f);
> }
> {code}
> This sets the configured template properties in the configuration object and then it overwrites the user limit factor and the maximum AM resource percent values with the hardcoded ones. The order should be reversed.
