--------------------------------------
Summary: Fix flaky
DedicatedMirrorIntegrationTest.testMultiNodeCluster
Key: KAFKA-16672
URL: https://issues.apache.org/jira/browse/KAFKA-16672
Project: Kafka
Issue Type: Test
Reporter: Chia-Ping Tsai
Assignee: Chia-Ping Tsai
It is flaky on my jenkins, and sometimes it fails in Kafka
[CI|https://ge.apache.org/scans/tests?search.buildOutcome=failure&search.buildToolType=gradle&search.relativeStartTime=P28D&search.rootProjectNames=kafka&search.timeZoneId=Asia%2FTaipei&tests.container=org.apache.kafka.connect.mirror.integration.DedicatedMirrorIntegrationTest&tests.test=testMultiNodeCluster()]
The error happens in virtue of race condition. `KafkaBasedLog` loads records
from topic via thread, so `RebalanceNeededException` will be thrown if we check
the task configs too soon. It seems to me `RebalanceNeededException` is a
temporary exception so we should treat it as a retryable exception in waiting.
