beijing-penguin removed a comment on issue #504: No route info of this topic problem

   建议main方法中代码设置config的优先级，应该大于控制台的传参。。。。而且哪怕我broker设置失效了，，，namesrv.log日志抛出一段诡异的exceptionCaught 127.0.0.1:49195   这种异常，rocketmq_client.log也只是抛出org.apache.rocketmq.client.exception.MQClientException: CODE: 17  DESC: No topic route info in name server for the topic: TopicTest
   See http://rocketmq.apache.org/docs/faq/ for further details.     这也不是本次操作失败的主要原因啊，主要是broker连接namesrv失败，get不到topic信息，而不是这里的No topic route info in name server for the topic。。。。建议服务端日志和client异常提示能够透明点。不要只是抛No route info of this topic problem。。应该把完整的连接错误和其他相关异常堆栈一起抛出来。  
   
   而且我broker启动的时候，本来就没连上namesrv的情况下，也应该给出warn或者error级别的提示信息。。现在默认只打印出来The broker[WIN-FMHILLP1PVS, localhost:10911] boot success. serializeType=ROCKETMQ and name server is localhost:8888，，只有success成功信息。
   没有namesrv连接失败的信息，，所以导致我也根本不知所云，排查问题很困难。
