> {{KafkaConsumer.partitionsFor}} method by it's signature returns a {{List<PartitionInfo>}}. Problem is that in case (metadata for) topic does not exist, current implementation will return null, which is considered a bad practice - instead of null it should return empty list.
> Root cause is that the Cluster collection returning methods are returning null.
