jihoonson opened a new pull request #6015: Check the kafka topic when comparing checkpoints from tasks with the one stored in metastore URL: https://github.com/apache/incubator-druid/pull/6015 The key change is: https://github.com/apache/incubator-druid/compare/master...jihoonson:supervisor-check-topic?expand=1#diff-6eee87b3aa4eb3a516965fe6e93e25a4R1191. If it doesn't check the topic, the supervisor considers the checkpoints in metastore invalid and tries to find something good offsets (earliest or latest) from Kafka. This causes offset mismatch and makes all tasks failed. Maybe this is not a bug because we don't support changing topic in the supervisor spec officially, but at least this patch fixes a weird behavior which makes debugging harder.
