Weiwei Yang commented on YARN-8896: ----------------------------------- Hi [~tangzhankun] The patch needs to update the doc as well, it is missing in this patch. Lets create one more Jira to get that done. Please take a look at \{{CapacityScheduler.md}} Thanks. > Limit the maximum number of container assignments per heartbeat > --------------------------------------------------------------- > > Key: YARN-8896 > URL: https://issues.apache.org/jira/browse/YARN-8896 > Project: Hadoop YARN > Issue Type: Improvement > Affects Versions: 2.9.0, 3.0.0 > Reporter: Weiwei Yang > Assignee: Zhankun Tang > Priority: Major > Fix For: 3.1.2, 3.2.1 > > Attachments: YARN-8896-trunk.001.patch > > > YARN-4161 adds a configuration > \{{yarn.scheduler.capacity.per-node-heartbeat.maximum-container-assignments}} > to control max number of container assignments per heartbeat, however the > default value is -1. This could potentially cause the CS gets stuck in the > while loop causing issue like YARN-8513. We should change this to a finite > number, e.g 100. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
