Weiwei Yang reassigned YARN-8212:
---------------------------------
Assignee: Tao Yang
> Pending backlog for async allocation threads should be configurable
> -------------------------------------------------------------------
>
> Key: YARN-8212
> URL: https://issues.apache.org/jira/browse/YARN-8212
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Weiwei Yang
> Assignee: Tao Yang
> Priority: Major
>
> During the perf testing, we found that when we scale up to 20k nodes, the
> backlog size is often full and cause allocation threads to wait. Hence, it's
> better to make this configurable so user can tune the perf with respect to
> different size of nodes.
