> From [~sseth] on review of HIVE-13620, in regards to
> LlapBaseInputFormat.getServiceInstance() and how to handle the case of no
> LLAP service instance for the host specified in the LLAP input split:
> {quote}
> 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.
