YunFan Zhou commented on YARN-7107: ----------------------------------- Hi, [~templedf]. I have uploaded my v1 patch. Please help me review the patch. Thank you. > add ability in Fair Scheduler to configure whether disable a queue > ------------------------------------------------------------------ > > Key: YARN-7107 > URL: https://issues.apache.org/jira/browse/YARN-7107 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: YunFan Zhou > Assignee: YunFan Zhou > Labels: fairscheduler > Attachments: YARN-7107.001.patch > > > In a production environment, emergency situations (such as the need to > calculate the important reports) as soon as possible we need to disable all > other queues, only allows the *RM* 's resources assigned to emergency queue > and other queue only at the end of the urgent tasks before allowing them to > be scheduled properly. > At present, our approach is to write a script, in the case of an emergency > manual changes all other queues' *minResources *and *maxResources * to *0mb, > 0vcores* and then rebase it.This is very troublesome and easy to make > mistakes. > So we need to add a configuration in the *FairScheduler* configuration to > indicate whether the queue is disabled, and if it is disabled, then *RM *will > not allocate resources to the queue. > * The child queue will integrate this property of the parent queue. > * If the child queue is configured with this property, the value of the child > queue configuration overrides the attributes of the parent queue. > * The default value of the root queue is *enabled*. > This will satisfy our needs, and I think other users will encounter such a > scenario.I think this is very applicable to everyone. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
