> This should really be a jira and TODO (post merge to master) - to either 1) go to an alternate random address from the available llap instances, or 2) have additional locations provided by HS2.
> I'd lean towards 1. It's absolutely possible for an llap instance to go down, or the node to go down, which would end up causing failures.
