> I'm using storm-kafka-0.8-plus for storm and kafka integration, storm spout works fine when parallelism is set to 1, but when to support increased event load, kafka-spout is set to parallelism > 1, but it seems to be kafka-spout does not distribute the load across the workers(some times, cases like higher parallelism, kafka-spout distribute the load on 3/4 workers but unpredictable distribution of tuples)
