      Description

      Set<String> racks = new TreeSet<>();
      for (DatanodeInfo dn : locs) {
        racks.add(dn.getNetworkLocation());
      }
      return new BlockPlacementStatusDefault(racks.size(), numberOfReplicas,
          clusterMap.getNumOfRacks());

      Here, HashMap should be used instead of TreeSet.
