--------------------------------------
Summary: Ensure consistency of checkpointed log start offset and
current log end offset
Key: KAFKA-8306
URL: https://issues.apache.org/jira/browse/KAFKA-8306
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
When initializing a log, we may use the checkpointed log start offset. We need
to ensure that the log end offset is set consistently with this value (i.e. it
must be greater than or equal to it). This may not always be true if the log
data is removed or has become corrupted. As a simple experiment, you can try
the following steps to reproduce the problem:
# Write some data to the partition
# Use DeleteRecords to advance log start
# Shutdown the broker
# Delete the log directory
# Restart the broker
You will see something like this in the logs:
{code:java}
[2019-04-29 11:55:21,259] INFO [Log partition=foo-0, dir=/tmp/kafka-logs]
Completed load of log with 1 segments, log start offset 10 and log end offset 0
in 36 ms (kafka.log.Log){code}
This may be the cause of KAFKA-8255, but I am not sure yet.
