[jira] [Commented] (YARN-6301) Fair scheduler docs should explain the meaning of setting a queue's weight to zero

It is almost clear to me now. One thing I'd like to make it clear that "ad hoc queue" only works among its sibling queues. If one queue under another parent-queue has demand for resource, the "ad hoc queue" can still have resource due to fairshare of its parent-queue. If I am wrong, please correct me. > Fair scheduler docs should explain the meaning of setting a queue's weight to > zero > -- > > Key: YARN-6301 > URL: https://issues.apache.org/jira/browse/YARN-6301 > Project: Hadoop YARN > Issue Type: Improvement > Components: fairscheduler >Affects Versions: 3.0.0-alpha2 >Reporter: Daniel Templeton >Assignee: Tao Jie > Labels: docs > Attachments: YARN-6301.001.patch, YARN-6301.002.patch > > -- This message was sent by Atlassian JIRA (v6.3.15#6346) - To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org

You're on the right track, but I'd like to be a little more explicit. A queue with weight 0 will not receive resources as long as there is demand from any other queue. A weight-0 queue is often called an "ad hoc queue." > Fair scheduler docs should explain the meaning of setting a queue's weight to > zero > -- > > Key: YARN-6301 > URL: https://issues.apache.org/jira/browse/YARN-6301 > Project: Hadoop YARN > Issue Type: Improvement > Components: fairscheduler >Affects Versions: 3.0.0-alpha2 >Reporter: Daniel Templeton >Assignee: Tao Jie > Labels: docs > Attachments: YARN-6301.001.patch > > -- This message was sent by Atlassian JIRA (v6.3.15#6346) - To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org

It seems to me that the queue could not get any share more than the MinResource in that case, am I correct? Should we add a non-negative check here since negative weight of queue is more confusing? > Fair scheduler docs should explain the meaning of setting a queue's weight to > zero > -- > > Key: YARN-6301 > URL: https://issues.apache.org/jira/browse/YARN-6301 > Project: Hadoop YARN > Issue Type: Improvement > Components: fairscheduler >Affects Versions: 3.0.0-alpha2 >Reporter: Daniel Templeton > Labels: docs > -- This message was sent by Atlassian JIRA (v6.3.15#6346) - To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
