-------------------------------
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
