Neha Narkhede commented on KAFKA-440:
-------------------------------------

My bad, I forgot to replace kafka_home in cluster_config.json. However, I'm 
sure people will forget to do the same as well. How about -

1. Defaulting kafka_home to the current project's home directory in the 
cluster_config.json using localhost. That means, the cluster_config.json that 
ships with kafka will not override kafka_home and will run on localhost by 
default.
2. On test startup, verify that the kafka_home directory exists. If not, exit 
the test with a meaningful error message.

> Initial requirements:
> 1. The whole test framework is preferably coded in Python (a common scripting 
> language which has well supported features)
> 2. Test framework driver should be generic (distributed environment can be 
> local host)
> 3. Test framework related configurations are defined in JSON format
> 4. Test environment, suite, case definitions may be defined in the following 
> levels:
>   4-a entity_id is used as a key for looking up related config from different 
> levels
>   4-b Cluster level defines: entity_id, hostname, kafka_home, java_home, ...
>   4-c Test suite / case level defines:
>     4-c-1 zookeeper: entity_id, clientPort, dataDir, log_filename, 
> config_filename
>     4-c-2 broker: entity_id, port, log.file.size, log.dir, log_filename, 
> config_filename
>     4-c-3 producer: entity_id, topic, threads, compression-codec, 
> message-size, log_filename, config_filename
