             Summary: System Test Transient Failure on testcase_0122
                 Key: KAFKA-772
                 URL: https://issues.apache.org/jira/browse/KAFKA-772
             Project: Kafka
          Issue Type: Bug
            Reporter: John Fung
         Attachments: testcase_0122.tar.gz

* This test case is failing randomly in the past few weeks. Please note there is a small % data loss allowance for the test case with Ack = 1. But the failure in this case is the mismatch of log segment checksum across the replicas.

* Test description:
3 brokers cluster
Replication factor = 3
No. topic = 2
No. partitions = 3
Controlled failure (kill -15)
Ack = 1

* Test case output
