I'm going to try bumping up the "numRetries" key in my producer config. Is this a good option in this case? I am using the zookeeper connect option so I'm aware that I may get stuck retrying to a failed node, but if it's just a temporary network glitch I'll at least get a bit more of a chance to recover.
