looks good to me. +1.
> Ozone: cannot enable test debug/trace log
> -----------------------------------------
>
> Key: HDFS-11977
> URL: https://issues.apache.org/jira/browse/HDFS-11977
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone, test
> Reporter: Tsz Wo Nicholas Sze
> Assignee: Tsz Wo Nicholas Sze

> 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:
> {code}
> @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");
> }
> {code}
> Output:
> {code}
