Kafka 0.10.0 Found a corrupted index file during Kafka broker startup

-deleted text-After force shutdown all kafka brokers one by one, restart them one by one, but a broker startup failure.

The following WARN leval log was found in the log file:
found a corrutped index file, xxxx.index , delet it ...

you can view details by following attachment.

~I look up some codes in core module, found out :

the nonthreadsafe method LogSegment.append(offset, messages) has tow caller:

1) Log.append(messages) // here has a synchronized lock
2) LogCleaner.cleanInto(topicAndPartition, source, dest, map, retainDeletes, messageFormatVersion) // here has not

So I guess this may be the reason for the repeated offset in 00000xx.log file (logsegment's .log) ~

Although this is just my inference, but I hope that this problem can be quickly repaired
