> Fair Scheduler: exception thrown when a parent queue marked 'parent' has
> configured child queues
> ------------------------------------------------------------------------------------------------
>
> Key: YARN-4975
> URL: https://issues.apache.org/jira/browse/YARN-4975
> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler
> Affects Versions: 2.7.2
> Reporter: Ashwin Shankar
> Assignee: Yufei Gu
> Attachments: YARN-4975.001.patch
>
>
> We upgraded our clusters to 2.7.2 from 2.4.1 and saw the following exception
> in RM logs :
> {code}
> Caused by:
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.AllocationConfigurationException:
> Both <reservation> and type="parent" found for queue root.adhoc which is
> unsupported
> at
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.AllocationFileLoaderService.loadQueue(AllocationFileLoaderService.java:519)
> at
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.AllocationFileLoaderService.reloadAllocations(AllocationFileLoaderService.java:352)
> at
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.initScheduler(FairScheduler.java:1440)
> {code}
> From the exception, it looks like we've configured 'reservation', but we've
> not. The issue is that AllocationFileLoaderService#loadQueue assumes that a
> parent queue marked as 'type=parent' cannot have configured child queues.
> That can be a problem in cases where we mark a queue as 'parent' which has no
> configured child queues to start with, but we can add child queues later on.
> Also the exception message is kind of misleading since we haven't configured
> 'reservation'.
> How to reproduce:
> Run fair scheduler with following queue config:
> {code}
> <queue name="p" type="parent">
> <weight>10</weight>
> <maxRunningApps>300</maxRunningApps>
> <queue name="c">
> <weight>3</weight>
> </queue>
> </queue>
> {code}
