> GenericEventHandler.printEventQueueDetails cause RM recovery cost too much
> time
> -------------------------------------------------------------------------------
>
> Key: YARN-10739
> URL: https://issues.apache.org/jira/browse/YARN-10739
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 3.4.0, 3.3.1, 3.2.3
> Reporter: Zhanqi Cai
> Assignee: Qi Zhu
> Priority: Critical
> Attachments: YARN-10739-001.patch, YARN-10739-002.patch,
> YARN-10739.003.patch, YARN-10739.003.patch
>
>
> Due to YARN-8995 YARN-10642 add GenericEventHandler.printEventQueueDetails on
> AsyncDispatcher, if the event queue size is too large, the
> printEventQueueDetails will cost too much time and RM take a long time to
> process.
> For example:
> If we have 4K nodes on cluster and 4K apps running, if we do switch and the
> node manager will register with RM, and RM will call NodesListManager to do
> RMAppNodeUpdateEvent, code like below:
> {code:java}
> for(RMApp app : rmContext.getRMApps().values()) {
> if (!app.isAppFinalStateStored()) {
> this.rmContext
> .getDispatcher()
> .getEventHandler()
> .handle(
> new RMAppNodeUpdateEvent(app.getApplicationId(), eventNode,
> appNodeUpdateType));
> }
> }{code}
> So the total event is 4k*4k=16 mil, during this window, the
> GenericEventHandler.printEventQueueDetails will print the event queue detail
> and be called frequently, once the event queue size reaches 1 mil+, the
> Iterator of the queue from printEventQueueDetails will be so slow refer to
> below:
> {code:java}
> private void printEventQueueDetails() {
> Iterator<Event> iterator = eventQueue.iterator();
> Map<Enum, Long> counterMap = new HashMap<>();
> while (iterator.hasNext()) {
> Enum eventType = iterator.next().getType();
> {code}
> Then RM recovery will cost too much time.....
> Refer to our log:
> {code:java}
> 2021-04-14 20:35:34,432 INFO event.AsyncDispatcher
> (AsyncDispatcher.java:handle(306)) - Size of event-queue is 12000000
> 2021-04-14 20:35:35,818 INFO event.AsyncDispatcher
> (AsyncDispatcher.java:printEventQueueDetails(291)) - Event type: KILL, Event
> record counter: 310836
> 2021-04-14 20:35:35,818 INFO event.AsyncDispatcher
> (AsyncDispatcher.java:printEventQueueDetails(291)) - Event type: NODE_UPDATE,
> Event record counter: 1103
> 2021-04-14 20:35:35,818 INFO event.AsyncDispatcher
> (AsyncDispatcher.java:printEventQueueDetails(291)) - Event type:
> NODE_REMOVED, Event record counter: 1
> 2021-04-14 20:35:35,818 INFO event.AsyncDispatcher
> (AsyncDispatcher.java:printEventQueueDetails(291)) - Event type: APP_REMOVED,
> Event record counter: 1
> {code}
> Between AsyncDispatcher.handle and printEventQueueDetails, here is more than
> 1s to do Iterator.
> I upload a file to ensure the printEventQueueDetails only be called one-time
> pre-30s.
