             Summary: Refreshing Default Node Label Expression of a queue does not reflect for running apps
                 Key: YARN-7108
                 URL: https://issues.apache.org/jira/browse/YARN-7108
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacity scheduler
    Affects Versions: 2.7.3
            Reporter: Prabhu Joseph


Refreshing a queue's default node label expression does not reflect for the running applications. 

Repro Steps:

4 node cluster, two node labels label1 and label2. label1 is Exclusive Partition with Node1 and Node2, label2 is Exclusive Partition with Node3 and Node4. A default queue whose default node label expression is label1. 

1.Shutdown NodeManagers on label1 nodes Node1 and Node2
2.Submit a sample mapreduce on default queue which will stay in ACCEPTED state 
3.Change default node label expression for default queue to label2 in capacity-scheduler.xml
yarn rmadmin -refreshQueues
queue's config gets reflected to label2 as shown on RM UI queue section but job still stays at ACCEPTED state
4. Submitting a new job into default queue moves into RUNNING state
