-------------------------------------------
Summary: 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: New Feature
Components: fairscheduler
Reporter: Wilfred Spiegelenburg
Assignee: 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)
