---------------------------------
Summary: empty active segment can trigger recovery after clean
shutdown and restart
Key: KAFKA-13603
URL: https://issues.apache.org/jira/browse/KAFKA-13603
Project: Kafka
Issue Type: Bug
Reporter: Cong Ding
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.
