Wangda Tan commented on YARN-7005: ---------------------------------- Thanks [~Tao Yang], the perf report looks really nice! Could you check the failed test cases, they might be related. [~sunilg] could u help with the patch review since I will on vacation until Jan 1st. > 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.
