Michael Noll commented on STORM-277:
------------------------------------
Amol,
from what I understand this issue is rather a problem in the Kafka spout of
wurstmeister, not in Storm itself. Hence I'd suggest for the moment to raise a
bug report at wurstmeister's storm-kafka-0.8-plus project on GitHub:
https://github.com/wurstmeister/storm-kafka-0.8-plus
I briefly checked the Issues page there, and I didn't see a ticket of yours
yet. Would you mind raising your bug report directly at wurstmeister's?
> Kafka-Spout does not support parallelism(unpredictable behaviour)

> 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)
