---------------------------------------
Summary: Transaction system test uses inconsistent timeouts
Key: KAFKA-10274
URL: https://issues.apache.org/jira/browse/KAFKA-10274
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
Assignee: Jason Gustafson
We've seen some failures in the transaction system test with errors like the
following:
{code}
copier-1 : Message copier didn't make enough progress in 30s. Current progress: 0
{code}
Looking at the consumer logs, we see the following messages repeating over and
over:
{code}
[2020-07-14 06:50:21,466] DEBUG [Consumer
clientId=consumer-transactions-test-consumer-group-1,
groupId=transactions-test-consumer-group] Fetching committed offsets for
partitions: [input-topic-1]
(org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)
[2020-07-14 06:50:21,468] DEBUG [Consumer
clientId=consumer-transactions-test-consumer-group-1,
groupId=transactions-test-consumer-group] Failed to fetch offset for partition
input-topic-1: There are unstable offsets that need to be cleared.
(org.apache.kafka.clients.consumer.internals.ConsumerCoordinator)
{code}
I think the problem is that the test implicitly depends on the transaction
timeout which has been configured to 40s even though it expects progress after
30s.
