Description

Interestingly, the test debug/trace logs are not printed for Ozone classes even if we invoke GenericTestUtils.setLogLevel(log, Level.ALL). Other classes such as Object do not have such problem. Here is a test:

  @Test
  public void testLogLevel() throws Exception {
    runTestLogLevel(StorageContainerManager.class);
    runTestLogLevel(Object.class);
  }
  static void runTestLogLevel(Class<?> clazz) throws Exception {
    final Logger log = LoggerFactory.getLogger(clazz);
    GenericTestUtils.setLogLevel(log, Level.ALL);
    log.trace(clazz.getSimpleName() + " trace log");
    log.debug(clazz.getSimpleName() + " debug log");
    log.info(clazz.getSimpleName() + " info log");
    log.warn(clazz.getSimpleName() + " warn log");
    log.error(clazz.getSimpleName() + " error log");
  }

Output:
