> Within a LogSegment, the TimeIndex and OffsetIndex are lazy indices that
> don't get created on disk until they are accessed for the first time. If the
> active segment is empty at the time of the clean shutdown, the disk will have
> only the log file but no index files.
> However, Log recovery logic expects the presence of an offset index file on
> disk for each segment, otherwise, the segment is considered corrupted.
> We need to address this issue: create the index files for empty active
> segments during clean shutdown.
