Github user revans2 commented on the pull request: https://github.com/apache/storm/pull/401#issuecomment-72102590 For the most part it looks good, I would like to see us use the cached assignment instead of going to zookeeper again to get it. I would also like to understand better how we avoid issues with downloading the same thing in two different threads. I'm not sure I understand the exact cause of what puts us in this situation to begin with, so I don't feel comfortable that we will not try to download the same thing twice and cause some issues when we do.
