Stevo Slavic updated KAFKA-2358:
--------------------------------
Description:
{{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.
