    Description

      yarn.scheduler.queue-placement-rules doesn't work as expected in Capacity Scheduler

      • *Queue Mapping Interface based on Default or User Defined Placement Rules* - This feature allows users to map a job to a specific queue based on some default placement rule. For instance based on user & group, or application name. User can also define their own placement rule.

      As per current UserGroupMapping is always added in placementRule. CapacityScheduler#updatePlacementRules

          // Initialize placement rules
          Collection<String> placementRuleStrs = conf.getStringCollection(
              YarnConfiguration.QUEUE_PLACEMENT_RULES);
          List<PlacementRule> placementRules = new ArrayList<>();
      ...
      
          // add UserGroupMappingPlacementRule if absent
          distingushRuleSet.add(YarnConfiguration.USER_GROUP_PLACEMENT_RULE);
      

      PlacementRule configuration order is not maintained
