Yes, those exceptions are fine. These are cases where we try to delete the node if it's there, but don't care if it's not there - things like that. In some of these cases, ZooKeeper logs things we can't stop, even though it's expected that sometimes we will try and remove nodes that are not there or create nodes that are already there.
