> * 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
