Description

Ambari UI can not save changes due to Ambari StackAdvisor failing if accessible-node-labels is used as a queue name:

2018-02-20 05:16:30,497 - Entered __getSelectedQueueTotalCap fn() with llap_daemon_selected_queue_name= 'llap'. 
2018-02-20 05:16:30,498 - DBG: Selected queue name as: yarn.scheduler.capacity.root.accessible-node-labels.llap.capacity 
2018-02-20 05:16:30,498 - Queue list : ['root', 'accessible-node-labels', 'llap'] 
2018-02-20 05:16:30,498 - DBG: Selected queue name as: yarn.scheduler.capacity.root.capacity 
2018-02-20 05:16:30,498 - Total capacity available for queue root is : 1187840.0 
Error occured in stack advisor.
