> AsyncDispatcher event queue backlog with millions of STATUS_UPDATE events
> -------------------------------------------------------------------------
>
> Key: YARN-11878
> URL: https://issues.apache.org/jira/browse/YARN-11878
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: api, RM
> Affects Versions: 3.4.0, 3.4.1
> Reporter: victor
> Priority: Major
> Labels: pull-request-available
>
> In large-scale YARN clusters with a high number of nodes, the AsyncDispatcher
> event queue can grow to several million events. More than 90% of these are
> STATUS_UPDATE events.
> Profiling shows that within StatusUpdateWhenHealthyTransition.transition,
> more than 90% of the CPU time is spent in:
> ContainerStatusPBImpl.getCapability()
> This method appears to repeatedly parse or build protobuf capability objects
> on every STATUS_UPDATE, causing severe CPU overhead.
> Observed Logs (excerpt):
> 2025-09-29 01:23:32,546 INFO event.AsyncDispatcher: Size of event-queue is
> 2256000
> 2025-09-29 01:23:32,544 INFO event.AsyncDispatcher: Event type:
> STATUS_UPDATE, Event record counter: 2081612
> 2025-09-29 01:23:32,544 INFO event.AsyncDispatcher: Event type: KILL, Event
> record counter: 27808
> 2025-09-29 01:23:32,543 INFO event.AsyncDispatcher: Event type: NODE_UPDATE,
> Event record counter: 224
> ...
> EVENT statistics example:
> STATUS_UPDATE: 2,081,612
> KILL: 27,808
> CONTAINER_FINISHED: 706
> NODE_USABLE: 207
