      Description

      • 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
