> 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
