---------------------------------------

             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.
