> I was banging my head trying to figure out why SOLR-5795 combined with SOLR-5823 wasn't working when I noticed something interesting as a result of some gratuituous logging:
> * the control server thinks it's in running in cloud mode, in a cluster consisting solely of itself, and acts as overseer
> * none of the nodes in the actual cluster being tested think they are the overseer
> ...i haven't dug in very deep, but i suspect that some combination of the control server starting up first and thinking it's part of zk is leading to it becoming the overseer, even thought it evidently never thinks it's one of the leaders/replicas of the cloud cluster.
> It's hard to see this problem w/o SOLR-5823 -- i'll update the patch there with a test showing hte problem, but i wanted to make sure it got tracked in it's own bug.
