@lazyval +1 to your idea. Making KafkaSpout depend on kafka kafka APIs is
heavier task.
> KafkaSpout to await for the topic
> ---------------------------------
>
> Key: STORM-391
> URL: https://issues.apache.org/jira/browse/STORM-391
> Project: Apache Storm
> Issue Type: Improvement
> Affects Versions: 0.9.2-incubating
> Reporter: Alexey Raga
> Assignee: Kai Sasaki
> Labels: features
>
> When topic does not yet exist and the consumer is asked to consume from it,
> the default behaviour for Kafka heigh-level consumer is to "await" for the
> topic without a failure.
> KafkaSpout currently fails trying to get the partition information about the
> topic that does not exist.
> It may be a good idea to have the same common behaviour in KafkaSpout and it
> can probably be implemented through the zookeeper watchers: if topic does not
> exist, then set up a watcher and don't do anything until it yields.
