This happened when you > configure {{yarn.scheduler.minimum-allocation-mb}} to zero. > The problem is in the code used by both Capacity Scheduler and Fair > Scheduler. {{scheduler.increment-allocation-mb}} is a concept in FS, but not > CS. So the common code in class RMAppManager passes the > {{yarn.scheduler.minimum-allocation-mb}} as incremental one because there is > no incremental one for CS when it tried to normalize the resource requests. > {code} > SchedulerUtils.normalizeRequest(amReq, scheduler.getResourceCalculator(), > scheduler.getClusterResource(), > scheduler.getMinimumResourceCapability(), > scheduler.getMaximumResourceCapability(), > scheduler.getMinimumResourceCapability()); --> incrementResource > should be passed here. > {code} -- 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
