the total capacity) and B(75%), both can run at > total cluster capacity. There are 2 applications, appX that runs on Queue A, > always asking for 1G containers(non-AM) and appY runs on Queue B asking for 2 > GB containers. > The user limit is high enough for the application to reach 100% of the > cluster resource. > appX is running at total cluster capacity, full with 1G containers releasing > only one container at a time. appY comes in with a request of 2GB container > but only 1 GB is free. Ideally, since appY is in the underserved queue, it > has higher priority and should reserve for its 2 GB request. Since this > request puts the alloc+reserve above total capacity of the cluster, > reservation is not made. appX comes in with a 1GB request and since 1GB is > still available, the request is allocated. > This can continue indefinitely causing priority inversion. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
