Description

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:

  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);
  }
