Summary: Remove dangling dynamic queues on reinitialization
Key: YARN-10714
URL: https://issues.apache.org/jira/browse/YARN-10714
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Andras Gyori
Assignee: Andras Gyori
Current logic does not handle orphaned auto created child queues. The following
example steps show a scenario in which it is possible to submit applications to
an orphaned queue, that has an invalid (already removed) ParentQueue.
# Auto create a queue root.a.a-auto
# Remove root.a from the config
# Reinitialize CS without restarting it (possible via mutation API)
# Submit application to root.a.a-auto, while root.a is a non-existent queue
