------------------------------
Summary: tightening the offset check in ReplicaFetcherThread
Key: KAFKA-3755
URL: https://issues.apache.org/jira/browse/KAFKA-3755
Project: Kafka
Issue Type: Improvement
Reporter: Jun Rao
Currently, in ReplicaFetcherThread.processPartitionData(), we have the
following code to make sure that the fetchOffset matches the log end offset.
if (fetchOffset != replica.logEndOffset.messageOffset)
throw new RuntimeException("Offset mismatch for partition %s: fetched
offset = %d, log end offset = %d.".format(topicAndPartition, fetchOffset,
replica.logEndOffset.messageOffset))
It would be useful to further assert that the first offset in the messageSet to
be appended to the log is >= than the log end offset.
