             Summary: Trident should support writing to multiple Kafka clusters
                 Key: STORM-1352
                 URL: https://issues.apache.org/jira/browse/STORM-1352
             Project: Apache Storm
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Current it is impossible to instantiate two instances of the 
{{TridentKafkaState}} class that write to different Kafka cluster. This is 
because that {{TridentKafkaState}} obtains the the location of the Kafka 
producer from configuration. Multiple instances can only get the same 
configuration in the {{prepare()}} method.

This jira proposes to introduce a configuration class like 
{{TridentKafkaConfig}} to allow multiple instances of {{TridentKafkaState}} to 
write to different Kafka clusters.
