> URL: https://issues.apache.org/jira/browse/AMBARI-19451
> Project: Ambari
> Issue Type: Bug
> Components: ambari-views
> Affects Versions: 2.5.0
> Reporter: Sangeeta Ravindran
> Assignee: Sangeeta Ravindran

>
> Per the Apache documentation for Yarn Node Labels
> (http://hadoop.apache.org/docs/r2.7.3/hadoop-yarn/hadoop-yarn-site/NodeLabel.html),
> queues that can only access nodes without labels are defined by setting the
> property "yarn.scheduler.capacity.<queue-path>.accessible-node-labels" with
> space as the value.
> Reproduction Steps:
> 1. In the Capacity Scheduler view (Yarn Queue Manager), create queues q1,q2,
> and set accessible node labels for root,q1,q2 but not for default queue
> 2. Since there is no way to specify a "space" as the value for accessible
> node labels via Yarn Queue Manager, add this property manually via yarn
> configs. i.e. In Yarn -> Configs -> Scheduler, manually add
> yarn.scheduler.capacity.root.default.accessible-node-labels= (space after the
> =)
> 3. Save the configuration and restart Resource Manager as required
> 4. Return to Yarn Queue Manager, and click the default queue. It shows an
> error - Label is not exist on cluster.
