> STORM-2548 replaced the KafkaSpoutConfig.builder() implementations with ones
> that don't set the key/value deserializer fields in KafkaSpoutConfig, but
> instead just sets the corresponding property in the kafkaProps map. This is a
> breaking change for applications that assume those properties are set after
> the builder is created.
> Code like the following would break.
> {quote}
> this.keyDeserializer = config.getKeyDeserializer().getClass();
> this.valueDeserializer = config.getValueDeserializer().getClass();
> {quote}
