      Description

      YARN-9868 introduced an unnecessary check if we have the following placement rule:

      [managedParentQueue].%primary_group

      Here, %primary_group is expected to be created if it doesn't exist. However, there is this validation code which is not necessary:

                } else if (mapping.getQueue().equals(PRIMARY_GROUP_MAPPING)) {
                  if (this.queueManager
                      .getQueue(groups.getGroups(user).get(0)) != null) {
                    return getPlacementContext(mapping,
                        groups.getGroups(user).get(0));
                  } else {
                    return null;
                  }
      

      We should revert this part to the original version:

                } else if (mapping.queue.equals(PRIMARY_GROUP_MAPPING)) {
                  return getPlacementContext(mapping, groups.getGroups(user).get(0));
              }
