--------------------------------
> KafkaSpout to await for the topic
> ---------------------------------
>
> Key: STORM-391
> URL: https://issues.apache.org/jira/browse/STORM-391
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-kafka
> 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.
