-
Thanx Everyone for the work here.
[~ctest.team] you can check {{TestFsNamesystem.java}} there is a
{{testInitAuditLoggers()}} which already tests most of the things. You can add
your case also in the same test. You can add at the end in same the same test
and do something like this to repro your issue :
{code:java}
// Test Configuring TopAuditLogger.
conf.set(DFSConfigKeys.DFS_NAMENODE_AUDIT_LOGGERS_KEY,
"org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger");
fsn = new FSNamesystem(conf, fsImage);
auditLoggers = fsn.getAuditLoggers();
assertEquals(1, auditLoggers.size());
assertThat(auditLoggers.get(0), instanceOf(TopAuditLogger.class));
{code}
Let me know, if you intend to write test for something else and facing
trouble, will try to help write one. :)

Let's try to do it in this JIRA if it doesn't take too long.
It is usually better to have complete patches.

I can try to write a test to do this, it may take some time. Should I
incorporate the test into this patch?

Íñigo Goiri commented on HDFS-15124:
Before closing this... just making sure there is no quick test we can add for
this.
What about initialize one with and without the TopAuditLogger and checking that
in each case it does the right thing?

The tests look reasonable.
We may want to fix the checkstyle.
Actually, is there a chance we can do:

[~elgoiri]
I have already run the 4 failed test classes with my patch in the official
docker image and all of them passed successfully.
I feel like the failures are not about the content in the patch. Actually the
content in the patch won't be executed if not setting
`dfs.namenode.audit.loggers` to
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`.
Could you please help to check whether these failures are due to some flakiness
in tests?
Thank you a lot!

I was using hadoop-2.10.0 and the FSNameSystem was using
{code:java}
public static final Log LOG = LogFactory.getLog(FSNamesystem.class);{code}

Should I use the 3.x.x version to do the fix? It seems that 3.x.x is using
org.slf4j.Logger but 2.x.x is using org.apache.commons.logging.Log for

I uploaded a new patch to do all these changes.
[~elgoiri] I am sorry I didn't use {} style for the LOG in FSNamesystem.java
because in FSNamesystem.java the LOG is `org.apache.commons.logging.Log`
instead of `org.slf4j.Logger`. The `org.apache.commons.logging.Log` doesn't
support
{code:java}
LOG.error("xxx {}", "yyy"){code}
Please let me know if anything else needed. Thank you!

Please make sure you don't add TopAuditLogger twice by setting
dfs.namenode.top.enabled to TopAuditLogger.

Thanks [~ctest.team] for the proposal, yes, I think it makes sense.
Just use the logger style with {}.

[~elgoiri] How about catch InstantiationException in
initAuditLoggers(Configuration conf)
It will look like:
{code:java}
private List initAuditLoggers(Configuration conf) {
// Initialize the custom access loggers if configured.
Collection alClasses =
conf.getTrimmedStringCollection(DFS_NAMENODE_AUDIT_LOGGERS_KEY);
List auditLoggers = Lists.newArrayList();
if (alClasses != null && !alClasses.isEmpty()) {
for (String className : alClasses) {
try {
AuditLogger logger;
if (DFS_NAMENODE_DEFAULT_AUDIT_LOGGER_NAME.equals(className)) {
logger = new DefaultAuditLogger();
} else {
logger = (AuditLogger) Class.forName(className).newInstance();
}
logger.initialize(conf);
auditLoggers.add(logger);
} catch (InstantiationException e) {
LOG.error("Instantiation Error For " + className);
throw new RuntimeException(e);
} catch (RuntimeException re) {
throw re;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
{code}
The log error message can be refined. I can upload another patch for this.

Íñigo Goiri commented on HDFS-15124:
In addition to the constructor, the exception for this case is a little verbose
and not intuitive.
Is there a way we can improve that too?
One can follow the full stack trace but it is buried...

[jira] [Commented] (HDFS-15124) Crashing bugs in NameNode when using a valid configuration for `dfs.namenode.audit.loggers`

[~weichiu] Thank you for your reply!
Yes. The default value can also add TopAuditLogger, but most users didn't read
the src code and don't know it.
If the users want to use TopAuditLogger and they directly set it to
TopAuditLogger (without understanding the src code), then the namenode will
crash.
I wrote a patch to add the default constructor for the TopAuditLogger which I
think can make this part more robust.

Wei-Chiu Chuang commented on HDFS-15124:
You shouldn't need to add TopAuditLogger to auditlogger configuration. As long
as dfs.namenode.top.enabled is true (default), it is added.
