[GitHub] storm issue #2147: STORM-2538: New kafka spout emits duplicate tuples

Github user hmcl commented on the issue:

    https://github.com/apache/storm/pull/2147
  
    @srdo @harshach @arunmahadevan in face of the Manual Partition assignment related [fixes](https://github.com/apache/storm/pull/2151/commits), there are two options. I believe in the email list we agreed to go with option #1, but I would like to make sure.
    
    1 - We disregard and close this PR. If we do so, we are implicitly telling the user that if they decide to use dynamic partition assignment they are at their own responsibility and it won't work with multiple parallelism. Currently the only implementation we support is `ManualPartitionSubscription`
    2 - We improve this code to make it work for the dynamic case.
