Varun Saxena commented on YARN-4000: ------------------------------------ Agree with using fail fast config. Although we should then use it for all other checks as well(removal of queue on RM restart as well). Will update a patch with that change as well. > RM crashes with NPE if leaf queue becomes parent queue during restart > --------------------------------------------------------------------- > > Key: YARN-4000 > URL: https://issues.apache.org/jira/browse/YARN-4000 > Project: Hadoop YARN > Issue Type: Bug > Components: capacityscheduler, resourcemanager > Affects Versions: 2.6.0 > Reporter: Jason Lowe > Assignee: Varun Saxena > > This is a similar situation to YARN-2308. If an application is active in > queue A and then the RM restarts with a changed capacity scheduler > configuration where queue A becomes a parent queue to other subqueues then > the RM will crash with a NullPointerException. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
