   I changed the related code to 
   ```
       for (Map.Entry<String, Long> entry : remoteMapping.entrySet()) {
         String key = entry.getKey();
         long localValue = localMapping.getOrDefault(key, 0L);
         localMapping.put(key, Math.max(entry.getValue(), localValue));
       }
   ```
   
   @tomscut Sir, please help me review it again. Thanks
