> Currently 'default' rule in queue placement policy,if applied,puts the app in root.default queue. It would be great if we can make 'default' rule optionally point to a different queue as default queue . This queue should be an existing queue,if not we fall back to root.default queue hence keeping this rule as terminal.
> This default queue can be a leaf queue or it can also be an parent queue if the 'default' rule is nested inside nestedUserQueue rule(YARN-1864).
