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
