> This case passes if brokers are set to partition = 1, replicas = 1
> It fails if brokers are set to partition = 5, replicas = 3 (consistently reproducible)
> This test case is set up as shown below.
> 1. Start 2 ZK as a cluster in Source
> 2. Start 2 ZK as a cluster in Target
> 3. Start 3 brokers as a cluster in Source (partition = 1, replicas = 1)
> 4. Start 3 brokers as a cluster in Target (partition = 1, replicas = 1)
> 5. Start 1 MM
> 6. Start ProducerPerformance to send some data
> 7. After Producer is done, start ConsoleConsumer to consume data
> 8. Stop all processes and validate if there is any data loss.
> 9. No failure is introduced to any process in this test
> Attached a tar file which contains the logs and system test output for both cases.
