[jira] [Created] (YARN-10411) Create an allowCreate flag for MappingRules

             Summary: Create an allowCreate flag for MappingRules
                 Key: YARN-10411
                 URL: https://issues.apache.org/jira/browse/YARN-10411
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Gergely Pollak
            Assignee: Gergely Pollak


We need to make queue auto creation configurable on a per rule basis, not only on a per queue basis in order to support FS placement rules.

Add an extra validation, which only accepts non existent queues as targets when the create flag is true. All current constraints should remain in place (eg. creation is only possible under managed parent), this should be an extra check to see if the rule allows the queue to be created.
