C＃Map使用“{”减少失败响应状态代码不表示成功：403（禁止） . “}有时401：需要凭据

在 mscorlib.dll 中发生 System.AggregateException 类型的未处理异常

内部异常： {"Response status code does not indicate success: 403 (Forbidden)."} 有时会得到： {"Response status code does not indicate success: 401 (Credentials required)."}

所有登录都是正确的 . Hadoop.Connect（）正确连接 .
