Github user rfarivar commented on a diff in the pull request: https://github.com/apache/storm/pull/885#discussion_r47586077 --- Diff: external/storm-kafka/src/jvm/storm/kafka/PartitionManager.java --- @@ -149,9 +150,9 @@ public EmitState next(SpoutOutputCollector collector) { } if ((tups != null) && tups.iterator().hasNext()) { - if(_spoutConfig.topicAsStreamId) { + if (!Strings.isNullOrEmpty(_spoutConfig.outputStreamId)) { --- End diff -- Isn't it an overkill to import a whole package (com.google.common.base.Strings) to only test for null or empty?
