John Fung commented on KAFKA-583:
---------------------------------

This issue can be reproduced consistently using the attached broker log segment 
files and zookeeper data.

Please do the followings to reproduce:

1. Check out the latest 0.8 branch

2. The attached data file "kafka_583_zk_kafka_data.tar.gz" contains the 
following directories:
    /tmp/zookeeper_0
    /tmp/kafka_server_1_logs
    /tmp/kafka_server_2_logs
    /tmp/kafka_server_3_logs

If your local "/tmp" directory also contains the above directories, please 
rename them.

3. Download "kafka_583_zk_kafka_data.tar.gz" and extract them to your local 
"/tmp" directory

4. Download "kafka_583_reproduce_issue.patch" and apply under <kafka_home>:
    patch -p0 -i kafka_583_reproduce_issue.patch

5. Build kafka as: <kafka_home> $ ./sbt update package

6. In <kafka_home>, execute "chmod u+x validate_data_and_log_segment.sh"

7. In <kafka_home>/system_test : execute "python -B system_test_runner.py"

8. Wait for about 1 min, when the following message is showing on the console:

=====================================================
*** Sleeping for 30 min ...
You may now run : <kafka_home>/run_simple_consumer.sh
=====================================================

execute this command under <kafka_home>: ./validate_data_and_log_segment.sh

9. The following will be showing:

$ ./validate_data_and_log_segment.sh

10. The message count in broker 3 partition 2 is different between 
SimpleConsumerShell & DumpLogSegments
