Not sure Gus I would blame the create collection code. To the best of my recollection, when the create collection call returns the collection IS fully created. This doesn't mean though (and that's the problem IMO) that the cluster state on the node that issued the collection creation call is aware of it: its cache of cluster state is updated async at a later point once Zookeeper watches decide it's time).
I would tend to blame the way cluster state is managed in general in the cluster. I didn't look at this test specifically, so the actual issue might still be different.
