-----------------------------------
Summary: Unset Ordering Policy of Leaf/Parent queue converted from
Parent/Leaf queue respectively
Key: YARN-9950
URL: https://issues.apache.org/jira/browse/YARN-9950
Project: Hadoop YARN
Issue Type: Sub-task
Components: capacity scheduler
Affects Versions: 3.3.0
Reporter: Prabhu Joseph
Assignee: Prabhu Joseph
RM fails to start when adding a queue (say root.A.A1) under a leaf queue (say
root.A) with ordering policy fifo.
YARN supports fifo or fair for leaf queue and utilization or
priority-utilization for parent queue. When the existing leaf queue (root.A)
becomes parent queue - the ordering policy (fifo or fair) has to be unset. Else
YARN RM will fail as fifo or fair is not a valid queue ordering policy for
parent queue.
Similarly while removing a queue, unset ordering policy of leaf queue which
converted from parent queue.
