[jira] [Created] (KAFKA-1983) TestEndToEndLatency can be unreliable after hard kill

Jun Rao created KAFKA-1983:
------------------------------

             Summary: TestEndToEndLatency can be unreliable after hard kill
                 Key: KAFKA-1983
                 URL: https://issues.apache.org/jira/browse/KAFKA-1983
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jun Rao


If you hard kill TestEndToEndLatency, the committed offset remains the last checkpointed one. However, more messages are now appended after the last checkpointed offset. When restarting TestEndToEndLatency, the consumer resumes from the last checkpointed offset and will report really low latency since it doesn't need to wait for a new message to be produced to read the next message.
