> YARN-3635 introduces PlacementRules for placing applications in queues. It is currently hardcoded to one rule, {{UserGroupMappingPlacementRule}}. This should be configurable as mentioned in the comments:{noformat} private void updatePlacementRules() throws IOException {
> List<PlacementRule> placementRules = new ArrayList<>();
> // Initialize UserGroupMappingPlacementRule
> // TODO, need make this defineable by configuration.
> UserGroupMappingPlacementRule ugRule = getUserGroupMappingPlacementRule();
> if (null != ugRule) {
> placementRules.add(ugRule);
> }
> rmContext.getQueuePlacementManager().updateRules(placementRules);
> }{noformat}
