Jiangjie Qin commented on KAFKA-4497:
-------------------------------------

I looked at the log cleaner code in 0.10.1.  There is a bug that could cause 
this problem. For each compressed message set, The time index should have the 
offset of the exact inner message with the largest timestamp, but in the log 
cleaner we are using the last message's offset in the last message set it reads 
into the read buffer. 

The current logic has a problem of generating a -1 offset for the compacted 
message sets even though the write buffer is not empty.

In log cleaner, we may read a few compressed message set into read buffer at a 
time, and compact out some messages from each of the compressed message set. 
Consider the following case:

The read buffer reads two message sets, MessageSet 1 and MessageSet 2. And 
after compaction, 
1. MessageSet 1 has retained messages [M1, M2]
2. MessageSet 2 does not have retained messages.

What Log Cleaner will do is to append [M1, M2] to the log but the 
OffsetOfTheLargestTimestamp will be -1 because the last message set is 
MessageSet 2 and it has no retained messages.

The fix is to update the {{OffsetOfLargestTimestamp}} together with the update 
of {{maxTimestamp}} (the same as we are doing in 
{{ByteBufferMessageSet.validateMessagesAndAssignOffsets()}}. 

I'll provide a patch.

> Hi all,
> we are facing an issue with latest kafka 0.10.1 and the log cleaner thread 
> with regards to the timeindex files. From the log of the log-cleaner we see 
> after startup that it tries to cleanup a topic called xdc_listing-status-v2 
> [1]. The topic is setup with log compaction [2] and the kafka cluster 
> configuration has log.cleaner enabled [3]. Looking at the log and the newly 
> created file [4], the cleaner seems to refer to tombstones prior to 
> epoch_time=0 - maybe because he finds messages, which don’t have a timestamp 
> at all (?). All producers and consumers are using 0.10.1 and the topics have 
> been created completely new, so I’m not sure, where this issue would come 
> from. The original timeindex file [5] seems to show only valid timestamps for 
> the mentioned offsets. I would also like to mention that the issue happened 
> in two independent datacenters at the same time, so I would rather expect an 
> application/producer issue instead of random disk failures. We didn’t have 
> the problem with 0.10.0 for around half a year, it appeared shortly after the 
> upgrade to 0.10.1.
> The puzzling message from the cleaner “cleaning prior to Fri Dec 02 16:35:50 
> CET 2016, discarding tombstones prior to Thu Jan 01 01:00:00 CET 1970” also 
> confuses me a bit. Does that mean, it does not find any log segments which 
> can be cleaned up or the last timestamp of the last log segment is somehow 
> broken/missing?
> I’m also a bit wondering, why the log cleaner thread stops completely after 
> an error with one topic. I would at least expect that it keeps on cleaning up 
> other topics, but apparently it doesn’t do that, e.g. it’s not even cleaning 
> the __consumer_offsets anymore.
