Eric Payne resolved YARN-7424. ------------------------------ Resolution: Invalid bq. In order to create the "desired" behavior, we would have to fundamentally change the way the capacity scheduler works, Closing > Capacity Scheduler Intra-queue preemption: add property to only preempt up to > configured MULP > --------------------------------------------------------------------------------------------- > > Key: YARN-7424 > URL: https://issues.apache.org/jira/browse/YARN-7424 > Project: Hadoop YARN > Issue Type: Improvement > Components: capacity scheduler, scheduler preemption > Affects Versions: 3.0.0-beta1, 2.8.2 > Reporter: Eric Payne > Assignee: Eric Payne > > If the queue's configured minimum user limit percent (MULP) is something > small like 1%, all users will max out well over their MULP until 100 users > have apps in the queue. Since the intra-queue preemption monitor tries to > balance the resource among the users, most of the time in this use case it > will be preempting containers on behalf of users that are already over their > MULP guarantee. > This JIRA proposes that a property should be provided so that a queue can be > configured to only preempt on behalf of a user until that user has reached > its MULP. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
