------------------------------------
Summary: FairScheduler: app usage can go to negative
Key: YARN-6158
URL: https://issues.apache.org/jira/browse/YARN-6158
Project: Hadoop YARN
Issue Type: Bug
Components: fairscheduler, resourcemanager
Affects Versions: 3.0.0-alpha2
Reporter: Miklos Szegedi
Assignee: Miklos Szegedi
FiCaSchedulerApp.containerCompleted checks, if the container being completed is
in the active list:
{code}
// Remove from the list of containers
if (null == liveContainers.remove(containerId)) {
return false;
}
{code}
Fair scheduler should do the same, otherwise multiple different container close
events leave the application with negative resource usage in
{{queue.getMetrics().releaseResources}} and {{attemptResourceUsage.decUsed}}
