Looking at http://storm.apache.org/releases/current/Fault-tolerance.html, it states that "If the worker continuously fails on startup and is unable to heartbeat to Nimbus, Nimbus will reassign the worker to another machine." What happens if the Storm cluster has a single worker node? Will the worker process just be restarted indefinitely, or is there some way to configure a cut off of how many times a worker process can be restarted?
