Sergey Shelukhin created YARN-9320: -------------------------------------- Summary: ConcurrentModificationException in capacity scheduler (updateQueueStatistics) Key: YARN-9320 URL: https://issues.apache.org/jira/browse/YARN-9320 Project: Hadoop YARN Issue Type: Bug Affects Versions: 2.9.3 Reporter: Sergey Shelukhin
We are running a snapshot of 2.9 branch, unfortunately I'm not sure off the top of my head what version it corresponds to. I can look it up if that's important, but I haven't found a bug like this so I suspect it would also affect a current version unless fixed by accident. {noformat} 2019-02-20 13:12:52,785 FATAL [SchedulerEventDispatcher:Event Processor] org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CSQueueUtils: queueCapacities.getNodePartitionsSet() changed java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextNode(HashMap.java:1437) at java.util.HashMap$KeyIterator.next(HashMap.java:1461) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CSQueueUtils.updateQueueStatistics(CSQueueUtils.java:303) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.LeafQueue.updateClusterResource(LeafQueue.java:1879) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.ParentQueue.updateClusterResource(ParentQueue.java:897) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.updateNodeLabelsAndQueueResource(CapacityScheduler.java:1775) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.handle(CapacityScheduler.java:1633) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.handle(CapacityScheduler.java:154) at org.apache.hadoop.yarn.event.EventDispatcher$EventProcessor.run(EventDispatcher.java:67) {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
