Amol Fasale commented on STORM-277:
-----------------------------------
Also the kafka having partitions number is same as number of parallelism of
kafka-spout, still the same behavior.
> Kafka-Spout does not support parallelism(sometimes unpredictable behaviour)

> Issue Type: Bug
> Reporter: Amol Fasale
> Labels: kafka-0.8
>
> 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)
