Let's let this method throw an exception. Then the calling TaskManager can
see the difference between `null` (= no further split) and `Exception` (=
something went wrong / is inconsistent).

> For flip-6, we will have ResourceManager and every JobManager as potential
> leader contender and retriever. We should separate them by using different
> zookeeper path.
> For example, the path could be /leader/resource-manaeger for RM. And for each
> JM, the path could be /leader/job-managers/JobID
