The log could be on "debug" level, as this situation can occur when the
JobManager failed tasks and unregistered them, but the cancel() messages have
not reached the TaskManager.
Since this is a valid situation, it should not cause a "WARN" message. In
general, all situations that are valid race conditions and that need not
indicate a corrupted state or lead to a failure / recovery should probably not
have a "WARN" level.

> 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
