### Question:
HadoopConfUtil { public static boolean contains(Configuration jobConf, String name) { if (StringUtils.isNotBlank(jobConf.get(name))) { return true; } else { return false; } }  static String getUserNameInConf(Configuration jobConf); static boolean contains(Configuration jobConf, String name); static String getQueueName(Configuration jobConf);  }### Answer:
@Test public void testContains() throws FileNotFoundException { final String JOB_CONF_FILE_NAME = "src/test/resources/job_1329348432655_0001_conf.xml"; Configuration jobConf = new Configuration(); jobConf.addResource(new FileInputStream(JOB_CONF_FILE_NAME)); assertTrue(HadoopConfUtil.contains(jobConf, Constants.USER_CONF_KEY_HADOOP2)); assertFalse(HadoopConfUtil.contains(jobConf, Constants.USER_CONF_KEY)); }
