LGTM. Just a small nit: I think it's the standard style to have a space between

[~kamrul], MAPREDUCE-6139.3.patch looks good to me as well.
I should have suggested this earlier but could you write a unit test for this
bug?
You can create a test with the logic similar to
{{o.a.h.mapred.TestTaskLogAppender}} as something like
{{o.a.h.yarn.TestContainerLogAppender}}.
./hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/test/java/org/apache/hadoop/yarn.
Add tesContainerLogAppenderWithSizeLimit with the regression scenario:
# Create a Logger {{claLog}}
# Create a CLA appender {{claAppender}} with size limit
# claLog.addAppender(claAppender)
# claLog.info(message1) with {{Object message1}} where message1.toString()
calls claLog.info(stringmessage).
# claAppender.close
Since you ended up fixing CLA in hadoop-yarn-common, this JIRA has to move to
YARN project.

IMHO this complexity is not necessary or even correct just to be able to deal
with accidental logging activity occurring when CLA.close is already in
progress.

--
Thanks again [~jira.shegalov] for your quick and informative comment.
Actually I tried the both options : 1. List based 2. using closed variable.
Both indeed work. If you think the closed variable based approach is better I
would go with that option. As soon as you reconfirm this, I will post a patch.

Thanks for the patch [~kamrul].
Reopening CLA violates the javadoc for
[Appender#close|https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Appender.html#close()]
1. Let us move
{code}closing = true;{code} before {code}if (tail != null){code}
2. undo the change try/finally

Thanks [~sjlee0] and [~jira.shegalov] for the active participation.
I was considering a little different approach that patch I upload in this JIRA.
Can you please review it?
Basically, instead of using the iterator based access , I'm using index based.
Therefore using LinkedList.
I did some basic testing. As soon as, I get more support, I will do the full
testing.

[~kamrul], I disagree with this approach for the following reasons:
1. it does not address the root cause, the CLA appender is never closed and
keeps accepting appends although it won't be able to get rid of them.
2. LinkedList is not a random access data structure. Every time you call
{{get}} you end up scanning half of the list on average

Thanks [~jira.shegalov] for you comments.
My comments inline
1. it does not address the root cause, the CLA appender is never closed and
keeps accepting appends although it won't be able to get rid of them.
I think it will ultimately be able to close all. Because the same list
structure is being appended and close is accessing to those new entries as
well. In my testing, I found a case, where close() started with 36 entries in
the list and ended up with 38 entries to dealt with. The extra 2 was appended
by indirect call from super,append() in the close() method. In other words,
list size is increasing at the end and close() will ultimately append them.
2. LinkedList is not a random access data structure. Every time you call get
you end up scanning half of the list on average
Agree with this comment. ArrayList or some other similar data structure could
help in this regard.

Gera Shegalov commented on MAPREDUCE-6139:

Hi [~kamrul], thanks for reporting the issue.
This occurs when there mapreduce.task.userlog.limit.kb 0. I recommend not to
use the original log limit implementation as it has other serious problems such
as the potential to lose the valuable diagnostic information in the tail and a
long delay until one can see the log to begin with. MAPREDUCE-5672 provided an
alternative based on RollingFileAppender that does not have these problems
which I recommend to start using.
Coming back to the problem in this scenario. One of the pending events in the
Queue generated a new warn LogEvent via Token.toString and modified the tail
queue while the iterator is still in progress in the {{close}} stack frame. I
would fix this as follows:
introduce instance boolean variable {{closed}} and set it to {{true}}
immediately when {{close}} is invoked. Then we can make CLA's {{append}} a nop
when {{closed}} is {{true}}.

Updates:
I added more debugging to find out how close() call is invoking append() call
in the same thread. I dump the call stacktrace for this scenarios. Btw, the is
the root cause of ConcurrentModificationException.
Case 1: When running with Pig + Oozie. Please note close() is calling append()
which modifies the Queue.

Sangjin Lee commented on MAPREDUCE-6139:
I think that call is there by design. The tail queue is an internal buffer and
that code is trying to write out the buffered log events. You'll also see
super.close() right below this for loop.
I think this is triggering the exception (not that it is the cause but that it
triggers the problem):
{noformat}
org.apache.commons.logging.impl.Log4JLogger.warn(Log4JLogger.java:197)
org.apache.hadoop.security.token.Token.getClassForIdentifier(Token.java:118)
{noformat}
I haven't thought much about this, but perhaps another way to solve this is to
modify append() not to use the tail queue if it is in the middle of a shutdown.

Thanks [~sjlee0] for the reply.
I agree with your suggestion and already started the testing process by
blocking append() when it is called from close().
Not sure if it is the cleaner approach.
I will update with my testing result.

Sangjin Lee commented on MAPREDUCE-6139:
Just off the top of my head, how about an approach where if the close() (or
shutdown) is in progress append() would simply call super.append() instead of
playing with the tail queue? Perhaps a boolean flag to indicate that a shutdown
is progress...
That might be better than blocking (?) append().

Wandering if it will create recursive call. Because, in this case,
super.append() is ultimately calling this append().

Mohammad Kamrul Islam commented on MAPREDUCE-6139:
--
I did some investigation/debugging and found the problem happened when
ContainerLogAppender.close() is iterating, the ContainerLogAppender.append()
was executing by other thread. So append() add an entry and then close() found
the ConcurrentModificationException.
The main question is : append() is a synchronized method and close() is within
synchronized block. The question is : how it is possible to execute both such
synchronized methods at the same time. Am I missing something?

Sangjin Lee commented on MAPREDUCE-6139:
[~kamrul], the line doesn't seem to match up with the 2.3.0 source.
ContainerLogAppender.close() is l.79-86 in 2.3.0, but your stack trace
indicates the exception occurs on line 94. Are there private changes to it?
Could you share the source in its entirety?
