> Skip unnecessary sorting and iterating process for child queues without
> pending resource to optimize schedule performance
> -------------------------------------------------------------------------------------------------------------------------
>
> Key: YARN-7005
> URL: https://issues.apache.org/jira/browse/YARN-7005
> Project: Hadoop YARN
> Issue Type: Improvement
> Affects Versions: 2.9.0, 3.0.0-alpha4
> Reporter: Tao Yang
> Attachments: YARN-7005.001.patch, YARN-7005.002.patch
>
>
> Nowadays even if there is only one pending app in a queue, the scheduling
> process will go through all queues anyway and costs most of time on sorting
> and iterating child queues in ParentQueue#assignContainersToChildQueues.
> IIUIC, queues that have no pending resource can be skipped for sorting and
> iterating process to reduce time cost, obviously for a cluster with many
> queues. Please feel free to correct me if I ignore something else. Thanks.
