/** A new configuration where the behavior of reading from the default 
   * resources can be turned off.
   * 
   * If the parameter {@code loadDefaults} is false, the new instance
   * will not load resources from the default files. 
   * @param loadDefaults specifies whether to load from the default files

  public Configuration(boolean loadDefaults) {
    this.loadDefaults = loadDefaults;

      LOG.debug(StringUtils.stringifyException(new IOException("config()")));
    }
    synchronized(Configuration.class) {
      REGISTRY.put(this, null);
    }
  }

错误信息：

	at org.apache.hadoop.conf.Configuration.<init>(Configuration.java:227)
	at org.apache.hadoop.conf.Configuration.<init>(Configuration.java:214)

原来是这段代码的原因，不准许debug下日志输出～～～～
