Ray Chiang updated YARN-5387:
-----------------------------
Issue Type: Sub-task (was: New Feature)
Parent: YARN-5397
> FairScheduler: add the ability to specify a parent queue to all placement
> rules
> -------------------------------------------------------------------------------

> Key: YARN-5387
> URL: https://issues.apache.org/jira/browse/YARN-5387
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: fairscheduler
> Reporter: Wilfred Spiegelenburg

> In the current placement policy there all rules generate a queue name under
> the root. The only exception is the nestedUserQueue rule. This rule allows a
> queue to be created under a parent queue defined by a second rule.
> Instead of creating new rules to also allow nested groups, secondary groups
> or nested queues for new rules that we think of we should generalise this by
> allowing a parent attribute to be specified in each rule like the create flag.
> The optional parent attribute for a rule should allow the following values:
> - empty (which is the same as not specifying the attribute)
> - a rule
> - a fixed value (with or without the root prefix)
