> It's possible for log cleaning to generate segments that have a gap of more
> than Int.MaxValue between their base offset and their last offset. It's not
> possible to index those segments since there's only 4 bytes available to
> store that difference. The broker will end up writing overflowed ints into
> the index, and doesn't detect that there is a problem until restarted, at
> which point you get one of these:
> 2015-03-16 20:35:49,632 FATAL [main] kafka.server.KafkaServerStartable -
> Fatal error during KafkaServerStartable startup. Prepare to shutdown
> java.lang.IllegalArgumentException: requirement failed: Corrupt index found,
> index file (/mnt/persistent/kafka-logs/topic/00000000000000000000.index) has
> non-zero size but the last offset is -1634293959 and the base offset is 0
