CapacitySchedulerQueueManager allows unsupported Queue hierarchy. When creating a queue with same name as an existing parent queue name - it has to fail with below. {code:java} Caused by: java.io.IOException: A is moved from:root.A to:root.B.A after refresh, which is not allowed.Caused by: java.io.IOException: A is moved from:root.A to:root.B.A after refresh, which is not allowed. at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacitySchedulerQueueManager.validateQueueHierarchy(CapacitySchedulerQueueManager.java:335) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacitySchedulerQueueManager.reinitializeQueues(CapacitySchedulerQueueManager.java:180) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.reinitializeQueues(CapacityScheduler.java:762) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.reinitialize(CapacityScheduler.java:473) ... 70 more {code} In Some cases, the error is not thrown while creating the queue but thrown at submission of job "Failed to submit application_1571677375269_0002 to YARN : Application application_1571677375269_0002 submitted by user : systest to non-leaf queue : B" Below scenarios are allowed but it should not {code} 1. It allows root.A.A1.B when root.B.B1 exists already. 1. Add root.A 2. Add root.A.A1 3. Add root.B 4. Add root.B.B1 5. Allows Add of root.A.A1.B 2. It allows two root queues: 1. Add root.A 2. Add root.B 3. Add root.A.A1 4. Allows Add of root.A.A1.root {code} Below scenario is handled properly: {code} 1. It does not allow root.B.A when root.A.A1 exists already. 1. Add root.A 2. Add root.B 3. Add root.A.A1 4. Does not Allow Add of root.B.A {code} This error handling has to be consistent in all scenarios. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
