Benson Qiu commented on YARN-6195:
----------------------------------
[~leftnoteasy], [~sunilg]]: Here's the approach I have right now, based on
[~jlowe]'s comments. Would appreciate any thoughts.
{code:title=CSQueueUtils#updateUsedCapacity|borderStyle=solid}
Set<String> nodeLabels = childQueue.getNodeLabelsForQueue();
// {some code omitted}
// QueueMetrics does not support per-label capacities,
// so we report the maximum across all labels.
for (String nodeLabel : nodeLabels) {
usedCapacity =
Math.max(queueCapacities.getUsedCapacity(nodeLabel), usedCapacity);
absoluteUsedCapacity =
Math.max(queueCapacities.getAbsoluteUsedCapacity(nodeLabel),
absoluteUsedCapacity);
}
queueMetrics.setUsedCapacity(usedCapacity);
queueMetrics.setAbsoluteUsedCapacity(absoluteUsedCapacity);
{code}
