David Arthur created KAFKA-14263: ------------------------------------ Summary: Investigate flaky upgrade_test.py (missing messages) Key: KAFKA-14263 URL: https://issues.apache.org/jira/browse/KAFKA-14263 Project: Kafka Issue Type: Test Affects Versions: 3.3.0 Reporter: David Arthur
During system tests, we occasionally see flaky failures of upgrade_test.py. Here is one such recent failure on the 3.3 branch: {code} Module: kafkatest.tests.core.upgrade_test Class: TestUpgrade Method: test_upgrade Arguments: { "compression_types": [ "none" ], "from_kafka_version": "0.9.0.1", "to_message_format_version": "0.9.0.1" } {code} {code} AssertionError("2 acked message did not make it to the Consumer. They are: [21017, 21014]. We validated that the first 2 of these missing messages correctly made it into Kafka's data files. This suggests they were lost on their way to the consumer.") {code} It would be good to try and reproduce these types of failures and see how we can make the test more robust. -- This message was sent by Atlassian Jira (v8.20.10#820010)
