Sunil G commented on YARN-5545:
-------------------------------
Thank you very much [~jlowe] for sharing use case and detailed analysis.
I think i understood now the intend here. We will be sticking with the existing
configuration set here, and introducing a much more flexible global queue
max-apps. So for those queues which are not configured per-queue level, and do
not have any capacity configured (in case of node labels and the the problem
mentioned in this jira) will be set to this new config (global queue max-apps).
So I think more or less, we could have below pseudo code to represent this
behavior.
{code}
maxApplications = conf.getMaximumApplicationsPerQueue(getQueuePath());
if (maxApplications < 0) {
int maxGlobalPerQueueApps = conf.getGlobalMaximumApplicationsPerQueue();
if(maxGlobalPerQueueApps > 0) {
maxApplications = maxGlobalPerQueueApps;
} else {
int maxSystemApps = conf.getMaximumSystemApplications();
maxApplications =
(int) (maxSystemApps * queueCapacities.getAbsoluteCapacity());
}
}
{code}
So in cases where there are no capacity configured for some labels in a queue,
we could make use of global queue max-apps configurations.
