> As an operations person it would be nice to manage Kafka rack awareness via
> Ambari. Ambari allows node rack information to be configured and this
> information can then be pulled in the Kafka stack and populated in the
> server.properties file for Kafka.
> Design:
> This stack change uses the /clusterHostInfo/all_hosts and
> /clusterHostInfo/all_racks paths and materializes them to a variable. Then it
> uses linear search to find this node in the list of all hosts and it's
> corresponding rack id. This information is then stored in a variable called
> rack and which is materialized during the configure method of the broker
> scripts.
> This stack change relies on the node rack information stored in Ambari
> therefore will enable both Ambari UI and Blueprints to be used for setting up
> Kafka broker rack information.
