        ... 56 more{noformat}

For example, configure: {noformat}  <property>
    <name>yarn.scheduler.capacity.root.queues</name>
    <value>default,a</value>
  </property>
  <property>
    <name>yarn.scheduler.capacity.root.accessible-node-labels</name>
    <value>x</value>
  </property>
  <property>
    <name>yarn.scheduler.capacity.root.default.accessible-node-labels</name>
    <value>x</value>
  </property>
  <property>
    <name>yarn.scheduler.capacity.root.default.accessible-node-labels.x.maximum-capacity</name>
    <value>100</value>
  </property>
  <property>
    <name>yarn.scheduler.capacity.root.default.accessible-node-labels.x.capacity</name>
    <value>100</value>
  </property>{noformat}
, i.e. root.default is using label x and root.a is not. Then the above exception is thrown
when refreshing the scheduler UI (/cluster/scheduler)
