> Hey all,
> i have a strange problem with our uat cluster of 3 kafka brokers.
> the __consumer_offsets topic was replicated to two instances and our disks
> ran full due to a wrong configuration of the log cleaner. We fixed the
> configuration and updated from 0.10.1.1 to 0.10.2.1 .
> Today i increased the replication of the __consumer_offsets topic to 3 and
> triggered replication to the third cluster via kafka-reassign-partitions.sh.
> That went well but i get many errors like
> {code}
> [2017-06-12 09:59:50,342] ERROR Found invalid messages during fetch for
> partition [__consumer_offsets,18] offset 0 error Record size is less than the
> minimum record overhead (14) (kafka.server.ReplicaFetcherThread)
> [2017-06-12 09:59:50,342] ERROR Found invalid messages during fetch for
> partition [__consumer_offsets,24] offset 0 error Record size is less than the
> minimum record overhead (14) (kafka.server.ReplicaFetcherThread)
> {code}
> Which i think are due to the full disk event.
> The log cleaner threads died on these wrong messages:
> {code}
> [2017-06-12 09:59:50,722] ERROR [kafka-log-cleaner-thread-0], Error due to
> (kafka.log.LogCleaner)
> org.apache.kafka.common.errors.CorruptRecordException: Record size is less
> than the minimum record overhead (14)
> [2017-06-12 09:59:50,722] INFO [kafka-log-cleaner-thread-0], Stopped
> (kafka.log.LogCleaner)
> {code}
> Looking at the file is see that some are truncated and some are jsut empty:
> $ ls -lsh 00000000000000594653.log
> 0 -rw-r--r-- 1 user user 100M Jun 12 11:00 00000000000000594653.log
> Sadly i do not have the logs any more from the disk full event itsself.
> I have three questions:
> * What is the best way to clean this up? Deleting the old log files and
> restarting the brokers?
> * Why did kafka not handle the disk full event well? Is this only affecting
> the cleanup or may we also loose data?
> * Is this maybe caused by the combination of upgrade and disk full?
> And last but not least: Keep up the good work. Kafka is really performing
> well while being easy to administer and has good documentation!
