---------------------------------
Summary: Ordering of operations in
StreamThread.shutdownTasksAndState may void at-least-once guarantees
Key: KAFKA-4561
URL: https://issues.apache.org/jira/browse/KAFKA-4561
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 0.10.2.0
Reporter: Damian Guy
Assignee: Damian Guy
Fix For: 0.10.2.0
In {{shutdownTasksAndState}} we currently commit offsets as the first step. If
a subsequent step throws an exception, i.e, flushing the producer, then this
would violate the at-least-once guarantees.
We need to commit after all other state has been flushed
