Sangjin Lee updated YARN-4779: ------------------------------ Component/s: scheduler-load-simulator > Fix AM container allocation logic in SLS > ---------------------------------------- > > Key: YARN-4779 > URL: https://issues.apache.org/jira/browse/YARN-4779 > Project: Hadoop YARN > Issue Type: Sub-task > Components: scheduler-load-simulator > Reporter: Wangda Tan > Assignee: Wangda Tan > Labels: oct16-medium > Attachments: YARN-4779.1.patch, YARN-4779.2.patch, YARN-4779.3.patch, > YARN-4779.4.patch > > > Currently, SLS uses unmanaged AM for simulated map-reduce applications. And > first allocated container for each app is considered to be the master > container. > This could be problematic when preemption happens. CapacityScheduler preempt > AM container at lowest priority, but the simulated AM container isn't > recognized by scheduler -- it is a normal container from scheduler's > perspective. > This JIRA tries to fix this logic: do the real AM allocation instead of using > unmanaged AM. -- 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
