> Assignee: Guozhang Wang

> This happened on streaming startup, on a clean installation, no existing folder. Here I was starting 4 instances of our streaming app on 4 machines and one threw this exception. Seems to me there’s a race condition somewhere when instances discover others, or something like that.
