--------------------------------------
Summary: OutOfSequence error should be fatal
Key: KAFKA-5347
URL: https://issues.apache.org/jira/browse/KAFKA-5347
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
Assignee: Apurva Mehta
If the producer sees an OutOfSequence error for a given partition, we currently
treat it as an abortable error. This makes some sense because OutOfSequence
won't prevent us from being able to send the EndTxn to abort the transaction.
The problem is that the producer, even after aborting, still won't be able to
send to the topic with an OutOfSequence. One way to deal with this is to ask
the user to call {{initTransactions()}} again to bump the epoch, but this is a
bit difficult to explain and could be dangerous since it renders zombie
checking less effective. Probably we should just consider OutOfSequence fatal
for the transactional producer.
