I think the best way to achieve this might be to add another field in the allocations file (say, nonpreempt) and verify the value specified is less than min. > Support guaranteed shares in the fair scheduler > --- > > Key: YARN-616 > URL: https://issues.apache.org/jira/browse/YARN-616 > Project: Hadoop YARN > Issue Type: New Feature > Components: scheduler >Affects Versions: 2.0.3-alpha >Reporter: Sandy Ryza >Assignee: Sandy Ryza > > A common requested feature in the fair scheduler is to reserve shares of the > cluster for queues that no other queue can trample on, even if they are > unused. -- This message is automatically generated by JIRA.

This means that, even with preemption, it can take some time for a queue to get the minimum resources it deserves. > Support guaranteed shares in the fair scheduler > --- > > Key: YARN-616 > URL: https://issues.apache.org/jira/browse/YARN-616 > Project: Hadoop YARN > Issue Type: New Feature > Components: scheduler >Affects Versions: 2.0.3-alpha >Reporter: Sandy Ryza >Assignee: Sandy Ryza > > A common requested feature in the fair scheduler is to reserve shares of the > cluster for queues that no other queue can trample on, even if they are > unused. -- This message is automatically generated by JIRA.
