Summary: bug when setAbsoluteCapacity(String label, float value)
Key: YARN-9020
URL: https://issues.apache.org/jira/browse/YARN-9020
Project: Hadoop YARN
Issue Type: Bug
Reporter: tianjuan
bug at setAbsoluteCapacity
private void deriveCapacityFromAbsoluteConfigurations(String label,
Resource clusterResource, ResourceCalculator rc, CSQueue childQueue) {
/*
* In case when queues are configured with absolute resources, it is better
* to update capacity/max-capacity etc w.r.t absolute resource as well. In
* case of computation, these values wont be used any more. However for
* metrics and UI, its better these values are pre-computed here itself.
*/
// 1. Update capacity as a float based on parent's minResource
childQueue.getQueueCapacities().setCapacity(label,
rc.divide(clusterResource,
childQueue.getQueueResourceQuotas().getEffectiveMinResource(label),
getQueueResourceQuotas().getEffectiveMinResource(label)));
// 2. Update max-capacity as a float based on parent's maxResource
childQueue.getQueueCapacities().setMaximumCapacity(label,
rc.divide(clusterResource,
childQueue.getQueueResourceQuotas().getEffectiveMaxResource(label),
getQueueResourceQuotas().getEffectiveMaxResource(label)));
// 3. Update absolute capacity as a float based on parent's minResource and
// cluster resource.
childQueue.getQueueCapacities().setAbsoluteCapacity(label,
(float) childQueue.getQueueCapacities().getCapacity()
/ getQueueCapacities().getAbsoluteCapacity(label));
