             Summary: Config update can leave queue settings in an inconsistent state
                 Key: YUNIKORN-1566
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1566
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: core - scheduler
            Reporter: Peter Bacsko


During config update, we apply new settings immediately.

This can cause problems, because changes that are already applied are not reverted back when we encounter an error in {{Queue.applyConf()}}.

Suggested approach:
* Run through the hierarchy in a dry-run like fashion, to see if there's any error
* If no error is returned, apply the new config
