Nick Allen commented on METRON-279:
-----------------------------------

Based on git history... 

I mistakenly added `metron_kafka` and `metron_hbase` roles as part of 
METRON-211 (silly me)
Then as part of METRON-223, we added the 'parser_invalid' and 'parser_error' 
topics to `metron_kafka`.
Unfortunately, the `metron_kafka` and `metron_hbase` roles were never being 
used.
The 'parser_invalid' and 'parser_error' topics were not being created as part 
of the deployment process.

Our testing could have passed METRON-223 because the topics were just 
auto-created.  If that's the case, then this is super-easy to fix and we can 
wrap this up.  The alternative is that I am totally wrong and confused and so I 
don't want to fix anything until I am enlightened.

> Hi,
> There are two roles available that try to accomplish the task of creating 
> default kafka topics:-
> -metron-kafka
> -metron_kafka_topics
>  
> We would need to purge one of them.
> The main.yml file for metron_kafka_topics has the following entries :-
> topics_to_create:
>   - { topic: "pcap",        num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "bro",         num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "yaf",         num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "snort",       num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "enrichments", num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
> Whereas main.yml file for metron_kafka has the following entries :-
> topics_to_create:
> - { topic: "pcap",        num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "bro",         num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "yaf",         num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "parser_invalid",         num_partitions: 1, replication_factor: 
> 1, retention_gb: 10 }
>   - { topic: "parser_error",         num_partitions: 1, replication_factor: 
> 1, retention_gb: 10 }
>   - { topic: "snort",       num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
>   - { topic: "enrichments", num_partitions: 1, replication_factor: 1, 
> retention_gb: 10 }
> So particularly  i see the topics "parser_error" and "parser_invalid" missing 
> in
> metron_kafka_topics/main.yml file.
> Regards,
> Neha
