@Lewuathe its just one kafka request right? . KafkaSpout makes one request
if that request fails than you'll get a exception and if that exception happens
to be UnknownTopic than you can do the sleep like you have it now. IMO its
better to rely on Kafka api and accept their exception than have a work around
using zookeeper. Also current code assumes that users always going to use kafka
zookeeper as part KafkaSpout config. This is not a right assumption users can
also give broker hosts instead kafka hosts. In that case KafkaSpout uses storm
zookeepers to store the offset info.
